Cog star quilt

Cog star quilt

I have used two star quilt blocks for this quilt pattern.  The interesting thing is that they have different names because the colour placement is different, but in fact the layout is the same for each block.  I’m pleased with the way that it has turned out and with all the secondary designs that show up when you keep looking at the quilt.  The quilt measures 52″ by 64″ and I have used 1.1/4 yard of red fabric and dark blue, 3/4 yard  light blue, 1.1/2 yards of white.

Cutting requirements for the cog star quilt pattern

3.1/2″ squares:  forty dark blue, forty white

3.7/8″ squares:  forty each in dark blue/white, twenty each in light blue/red, forty each in light blue/white, twenty each in dark blue/red

2.1/2″ red strips: cut six strips for the border

Use all the 3.7/8″ squares in the colour combinations listed above to make half square triangles.  Place two squares with right sides together and mark a line along the diagonal.  Sew a 1/4″ seam either side of the marked line and cut along the line to produce two half square triangles.  These are now 3.1/2″ squares.  Press the seam towards the darker fabric and trim the corners where the triangle tips stick out.

The star quilt block with the white star is called the cog block.  Lay the squares out in four rows of four.  There are four 3.1/2″ squares in the corners, four red/light blue half square triangles in the middle forming a red square and eight dark blue/white half square triangles around the edges of the block.  Sew the squares together across each row and then sew the rows together.  Make ten of these.



Make the eight pointed star quilt block

The second star quilt block is known as the eight pointed star block.  It has a light blue star but the same red centre.  There are four white 3.1/2″ white squares in the corners, four dark blue/red half square triangles in the centre forming a red square and eight light blue/white half square triangles around the edges of the block.  Sew the squares together across each row and then sew the rows together.  Make ten of these also.

Alternate the two star quilt blocks

Sew the quilt blocks together in pairs and then fours, alternating the two different blocks.  This gives you five rows of four blocks.  Sew the rows together with each row starting with an alternate block:  row one beginning with the cog block, row two beginning with the eight pointed star block and so on.




Cog star quilt binding

For the border, make four strips of 2.1/2″ red fabric, two at 48.1/2″ long for the top and bottom and two at 64.1/2″ long for the sides.

The cog star quilt top is now complete and ready for layering, quilting and binding.

Thanks so much to all of you who have left comments – I seem to get loads of spam comments that are sometimes quite obscene, so it’s lovely to see the genuine comments from you!

  1. Rosemary…Thank you for making the correction. Had I read through the entire list of cuts, I would have known there was a discrepancy. In this case, I purchased the yardage from a printed note. I’m making the quilt as a gift and all is not totally lost. Even though I’ve cut a number of squares, I don’t want to start over, so I’m going to get creative with the remaining forty dark blue squares by selecting another fabric…it’s a quilt and the person receiving it won’t be any wiser! I enjoy your site and will continue to use it.

    • Hi Mae. Thanks for your understanding. I’m sure the quilt will look great with an extra fabric added in. As you say, the recipient will think that it is part of the design.

  2. Hello Rose…
    The Cog Star Quilt design is the second one I’m using from your site. I purchased the yardage recommended, however, I’m finding that the 3/4 yards for the dark blue and light blue is not enough to get all of the 3-1/2″ and 3-7/8″ squares needed for the quilt. I’m thinking I need at least 1-1/2 yards total for each. Has anyone else reported the same? I’m disappointed because I don’t know if I will be able to find the fabric as I purchased it weeks ago.

    • Hi Mae. I have taken another look at the pattern and you are absolutely right about the dark blue fabric. My sincere apologies – I have amended the pattern to read 1.1/4 yards of dark blue and I can only apologise for getting it wrong.

    Thanks Rose for this Pattern.
    I have finished the Cog Star Quilt. I did it
    in Pinks and Cream and it looks lovely and I am very pleased with the way
    it came out. I found your intructions very easy to follow—Thank you

  4. Liz Erasmus says:

    Many thanks for all your hard work putting these stunning ideas together. You have made quilting so easy to understand and do. Greeting from South Africa

  5. Hi Rose,

    I have only recently started receiving your tutorials and I am so pleased that I have, I find them a real inspiration. I especially like this latest design. Your finished quilt looks amazing. Thank you so much for sharing…..x

  6. Rose, I have been enjoying your site for a long while, but really like this latest pattern!
    It will have to wait tho’ as I just bought the cloth to make an “echidnas quilt” for my friends country cottage, where we saw an echidna during our visit.
    You have so many correspondants…all quilting …have you ever thought of having an e-quilt show on your site, so we can show you how you inspire us?

    • Thanks, Carol. I’m glad you like the pattern. I’m embarrassed to admit that I had to look up what an echidna is! Yes, I have often been asked about a gallery but so far I haven’t worked out how to do it. I will keep working on it, though. rose

      • Sorry Rose, I see replies often put their address…I’m sewing in Melbourne (Aus) where the Autumn colours are several weeks late this year, after a sizzling summer.
        Echidnas are somewhat rare anteaters ,egg laying like platupi, but look like a pin cushion if they see you coming as they burrow down.Will try to send pic when the project is done…but I’m no IT whizz either

        • Thanks for that, Carol – lovely to hear about your wildlife. The echidnas sound lovely. Love to see the photo of the finished quilt. rose

  7. Dear Rose. I also like all the Tutorials you do telling us what size and color of fabric we need ,then cutting them out sewing them together so we see how they go together. I would like for you to do a Tutorial on the (Folded Log cabin ) if you will, there are parts I have trouble understanding. I know it will be a lot of work. I would appreciate it! May you have great life many Blessing. P.S. I also have a light come on when my bobbin is low, I always thought it was to let me know the bobbin thread was low so keep an eye it. on it

  8. Thank you so much Rose for the inspiration for quilting you come up with great tutorials and make it look so simple. I appreciate all you do for us to make it look so simple. You are appreciated.

  9. Chris Sheldon says:

    Rose, I love getting your emails and watching your tutorials. I just made my first quilt 3 weeks ago and used your website and tutorial for Trip Around The World. Thank you so much for sharing. Chris @ Council Bluffs, IA, USA.

  10. Sue Chapman says:

    Thanks so much, Rose! These are two really beautiful squares!

  11. Hi Rose,
    You make everything look so easy. I have always been told I make things harder for me, but after looking at the instructions for this Cog Star, how could they be easier!! You have such great ideas and I like the way you put a twist on existing patterns. Thank you again!

  12. I too love your quilts and agree that to run out of thread on the bobbin is extremely frustrating. It has happened to me too. I expect it happens to most quilters at some time.
    Isn’t it amazing that one pattern can look so different using different colours.

    • Hi Pat. I’ve now been told that the machines that beep when your bobbin runs out aren’t very accurate and beep long before the bobbin really runs out, so now I feel better about not having one! I was amazed at the way one star looked larger than the other even though they were the same size. rose

  13. Marie Ellis says:

    Hi Rose
    I’ve been following your tutorials for over a year and have made a few quilts using your guidelines . I began quilting about five years ago ,then I discovered your tutorials I’ve made several lovely quilts and always eagerly await your next quilt design , I’m eager to do a simple appliqué quilt for a baby, do you have any plans to do a demo on appliqué ? Keep up your excellent work it’s much appreciated

    • Hi Marie. Thanks for your comments. I’m conscious that I have very little applique on the website and will try to do something about that soon. rose

  14. Carole Groom. says:

    Hi Rose, many thanks for your beutifull quilt patterns. There are so many to pick from that I cannot keep up with you. I have made a couple so far, I also loved the man’s neck tie project and went round the charity shops to buy some ties. My friends also gave me a lot, but when I changed over computers I seemed to have lost quite a few of your pattern including the tie one. Is there any chance of you repeating it, or sending me a copy through my email. I have a young lady at the caft club which I run who is also interested to make some thing from her grandfather’s ties. (He has recently past away and they were very close) . So please keep up the good work and keep the patterns comming. Thank you again. Carole.

    nice one rose. stars are my favorite! thanks

  16. Shirley McCormick says:

    Hi Rose, I want to make a throw-over quilt approx. 50x50inches square. The fabric I have for the middle of the block are pictures of kittens. They are slightly oblong. The finished measurements are as follows:- 5″ x 5 & 3/8th. I was thinking of adding strips of fabric with the top and bottom being slightly wider to bring it to a square. The joining blocks I thought to have a small three inch square in the middle and make it like a lattice with the corners of two rows of a darker colour to the sides & top & bottom. The fabric I have is more autumn colours . Kittens are white persian, white with a touch of ginger and vice versa or ginger tabby which is darker brown who has green eyes and the others blue. The background colour on some has green foliage and small flowers or grass: the white fluffy has a dk brown background with two dried ears of corn hanging down and a apple autumn green and a bit of muted red on it underneath. The dk brown tabby has a brownish/lt brown bird on a thin autumn leafy branch. I have enough kitten blocks to make two throw-over quilts which I want to make and give to the local cat-haven to raffle and raise some much needed money as they do not get any government assistance. Can you help me please. You may change my ideas how to make these quilts. You may have a better idea how to go about it. I am open to any suggestions. Greatfully yours, Shirley, Mandurah, Western Australia.

  17. Shirley McCormick says:

    Good morning Rose, I read all the lovely comments you have received from all over the world. Yes, I look forward to seeing all the lovely quilts you have designed. I have downloaded quite a few and they are in my files ready for when I need a different design for a quilt. Keep up the lovely work. Kind regards from Shirley, Mandurah, Western Australia.

  18. Thanks once again for a great quilt idea Rose. Each Saturday morning I eagerly open my emails to find what you have for us this week. I do all my patchwork by hand, usually while watching cricket!
    Cheers from Ballarat, Australia.

  19. Rose; Love your site & quilt patterns. I was just reading the instructions for the Cog Star Quilt Pattern and I am a bit confused!! The instructions for the Cog Star state: There are four 3 1/2″ squares in corners, four RED/WHITE HALF SQUARE TRIANGLES in the middle forming a red square. The pictures DO NOT show RED/WHITE half square triangles – but rather RED/LIGHT BLUE SQUARE TRIANGLES. Should the instructions read as:: RED/LIGHT BLUE HALF SQUARE TRIANGLES??
    I have copied and saved the pattern for Cog Star Quilt Pattern as I love this pattern and plan to make it in the future.
    Just wondering. Thanks

    • Oops! Thanks so much, Leona. You are absolutely right and I have just corrected it on the pattern. Thanks for pointing it out. rose

  20. If I wanted to make this in a double or queen size quilt – how much more material would I need and would I lay it out the same? I am much like Carolyn McAllaster – in that having retired from working at 75 I have started quilting and find it exciting to try new patterns. Thank you.

    • Hi Julia. You can make the quilt as large as you like. Just add more blocks per row or more rows. I used twenty blocks in this quilt, so if you used thirty blocks you could have six rows of five. The quilt would be 60″ by 72″. If you used forty two blocks the quilt would be seven rows of six, measuring 72″ by 84″ – that’s without the border. You would then need just over twice as much fabric as I used. Hope that helps. rose

  21. Another great design and wonderful instructions. Love your tutorials!! I wish I didn’t have to work & could just sew every day!!

  22. Ginette says:

    I love this quilt and the tutorial is so easy to follow. This is going to be my next project. Thanks.

  23. Phyllis says:

    Hi Rose!
    What a beautiful quilt today. It does have many designs to find in it and you certainly made it look easy. It makes me so happy to read all the responses from other quilters. Each one is enjoying your work as much as I do and that is great. Enjoy the new machine. Mine is about 6 yrs. old now and I’m still learning new ways to use it.


    • Hi Phyllis. Glad you like the quilt. I’ve been truly blessed with all the kind things people have been saying today. I think that I’ll probably be the same with my sewing machine – still learning for years to come. rose

  24. STELLA EVANS says:


  25. Hi Rose, just love your quilts. Wish I was half as cleaver as you, and such wonderful ideas you come up with. Please keep them coming I am in awe of your wonderful work and look so forward to each and every one you do. I do charity work so am considering making the cog block for someone who I know will enjoy it as much as I will enjoy making it.

  26. Cecilia Alcantar says:

    As always, you make the best tutorials,user friendly.
    I honestly have experienced a love of quilting because of you.
    Keep on keeping on.
    Cecilia Alcantar

  27. Hi Rose,
    Your are my absolute favorite quilt blogger as your tutorials are always so clear and easy to understand (especially for a “senior” newbie quilter!) And your designs are so pretty. I look forward to receiving your updates. Thank you for the inspiration and sharing your knowledge.

  28. Sandy McClellan says:

    I love each and everyone of your quilts. Thank you for so many great tutorials. Sandy

  29. As always more beautiful works of art.
    Thankyou so much for all your inspiring quilts.


  30. Hello Rose,
    thought I was the only one bothered by the bobbin thread running out, always at the wrong time! thanks for the inspirations. Marion

    • Hi Marion. Someone said to me that they sew their straightest seams without thread! Nice long row of holes in the fabric. rose

      • Re the beep for bobbin running out: My machine has one, but it is definitey not fool-proof. If you stop and change bobbins whenever it beeps, you waste a good amount of thread.

  31. Thank you for the wonderful tutorial. i love star quilts and this one is adorable!
    God bless, Thea

  32. dottie bishaw says:

    What a wonderful quilt pattern! Love all the patterns you do for all of us quilters. We really appreciate it. Thank-you again for sharing.

  33. Carol Bowers says:

    Love this, have seen the pattern but you make it so easy to make, and I was making it harder. Thanks and have saved for future use. Have a good day.

  34. Marge Tarleton says:

    Very nice and as complicated as it looks to make it is easy. You are an inspiration Rose to me !!!

  35. Maria Rakaska says:

    A note to Elizabeth-the blocks finished are 12″ square. Your table runner can be one row wide by 4 blocks or 6 blocks Or it can be 2 rows wide by
    6 blocks or 8 blocks. One thing I do for table runners is press the seams open for a flat finish so you can keep a vase on top or maybe a lazy-susan.
    This is a nice change from traditional block have the center square on point.
    Very pretty.

    • Hi Maria. Not sure if this one is meant for me – but if it is, then yes you could definitely use the star block for a table runner. Rose

    • Hi Maria. Sorry – I had lost Elizabeth’s comment when I first replied to yours – hence my confusion. That’s a really good idea to press the seams open. Now why didn’t I think of that! rose

  36. Hi rose
    You always come up with the nicest patterns. I enjoy your postings.
    Get all excited when I see a new posting of yours.
    Keep up the good work.

  37. Elizabeth says:


    • Sorry, Elizabeth – I lost your comment somehow. The blocks are 12″ finished size and could easily be used for a table runner or place mats. rose

  38. Carolyn McAllister says:

    Thank you for your clear directions. I am new to this hobby and am having a grand time learning something new at the age of 73. I bought a darling 1955 Singer Featherweight machine ( no computer chips in it) and am having a ball using your directions for Quilt-as you Go. Happy Spring from Pennsylvania.

    • Thanks for your comments, Carolyn. That’s what I love about quilting – it can be done with no extra equipment, leaving more money for fabric! rose

  39. This looks like a block that I want to try. I like the shading, almost making it look like a print and a negative. Thanks for you site. I enjoy looking at your posts and save many of them. I appreciate that you show us how blocks look when put together.

  40. Thank you for sharing your amazing talents with us. I was also very pleasantly surprised to find you in the Quilt On Line magazine which I just subscribed to and seeing your picture. You are as lovely as your quilts. I also enjoy hearing about your wonderful fur babies. They are Newfies, right? I love the new look on the site, thank you so much.

    • Thanks for your comments, Betty. Yes, Jody produces a really great magazine, doesn’t she – full of information. No, I don’t have any animals any more – that must be Penny at the Quilting Coach that you’re thinking of. rose

  41. Robyn Bursill says:

    Hi Rose,
    I love to see what you bring us each week. This design I really love and I like the colours you have used. It makes a beautiful quilt. I congratulate you on being a truely wonderful teacher and I thank you for being a giver of your gift of quilting.
    Robyn (Engadine, Australia – very wet at the moment)

    • Thank you, Robyn. That’s really kind of you to say so. I’m allowed to boast about our sunshine because it’s so rare for us to see the sun! rose

  42. Elizabeth says:


  43. Rose: It’s truly unfortunate that people have nothing better to do than degrade everything. I feel so sorry for their pitiful lives but always remember they have the problem, you don’t. We who have a love of life enjoy your sharing of patterns, information and experience. Thank you for your positive outlook on life and quilting.

    • Thanks for your comments. Don’t worry – the spam comments aren’t aimed at me. They are just people trying to get links in to their porn sites or whatever. rose

  44. Arlette in New York says:

    Wow — I love this quilt! I’m going to break out the Accuquilt Go to make all the triangles. Planning on making it in pink for a friend’s granddaughter due in August. Thanks for the inspiration!

  45. Sandra Woodhead says:

    Thank you so much for your wonderfully clear descriptions of the techniques you use. I love looking round your site for inspiration and guidance.

  46. Ahhh Rose, I love this new quilt you’ve given us today – so pretty. As for your wanting a machine that has a bobbin re-fill reminder – I wish I had one too! Too many times I have been zipping right along only to discover I ran out of thread in the bobbin…what a nuisance – anyhoooooo do love the Cog Star and your blog… enjoy my newsletter from you too…..have a happy weekend.

    • Thanks, Mitts. Glad you like the pattern. Yes, it’s often the seams without thread that turn out the best, isn’t it! rose

  47. I truly enjoy your postings. Quilting is my passion and I have learned so much from you.
    Thanks so much for sharing your gift of quilting.
    Mary B

  48. Thank you so much for the lovely blocks and clear tutorial. It produces a truly wonderful quilt and one I’m eager to (try) make! You’re my inspiration. Janie from USA.
