Square and Half Quilt

Square and a half quilt

The square and a half quilt (I know it’s not a very imaginative name!) is made using one quilt block only but it has the look of a quilt carefully designed with two very different blocks.  I just love it when that happens.  I’ve used nine square and a half quilt blocks to make this 55″ square quilt, using 3/4 yard of green, 1 yard each of dark blue and white, with 1.1/4 yards of light blue.

Cutting requirements for the square and a half quilt

3.7/8″ squares:  fifty four each in dark blue and white

3.1/2″ squares:  nine green, thirty six white, thirty six light blue

4.1/4″ squares:  eighteen green, nine light blue, nine dark blue

Use the 3.7/8″ squares to make half square triangles.  Place a white square and a dark blue square 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.  This will produce two half square triangles which are 3.1/2″ squares.

Press the seam allowance towards the dark fabric and trim the corners of the square.  Put these to one side now so that they don’t get confused with the quarter square triangles made in the next step.

Use the 4.1/4″ squares to make half square triangles as above, using one green square with either a light blue or a dark blue square.

Place one green/light blue half square triangle right sides together with a green/dark blue half square triangle.  Make sure that the green on one square is placed against the blue in the other square.  Mark a line along the other diagonal – so that it crosses the seam.  Sew a 1/4″ seam either side of the marked line and cut along the line.

This produces two quarter square triangles which are now 3.1/2″ squares.  Each one has two green quarters opposite each other and a light blue and a dark blue quarter opposite each other.

Making the square and a half quilt block

I think it will be easier to see the layout of the block if I show you the middle first.  This is nine patches with a green square in the middle, a light blue square in each corner and a quarter square triangle unit against each edge of the central square.  Note that these are placed so that the dark blue triangle is always along the edge of the green square.

Now it’s a simple matter to add the outer layer of the quilt block.  There’s a white square in the middle of each edge and dark blue/white half square triangles everywhere else.  These are placed so that the dark blue triangles seem to cut across the corner of the block.  In each corner there are three half square triangles and these are placed so that the triangles are facing the same way as each other in each corner.

Sew the squares together across each of the five rows and then sew the rows to each other.  You will need nine of these quilt blocks.

Assembling the square and a half quilt

This is a terribly easy quilt layout – just sew the quilt blocks together in three rows of three.

Quilt border

I have used three borders to frame this quilt.  The first border is made using 2.1/2″ strips of light blue fabric.  You will need two lengths of 45.1/2″ for the top and bottom of the quilt and two lengths of 49.1/2″ for the sides.

For the second border I have used 1.1/2″ strips of the green fabric.  Make two lengths of 49.1/2″ for the top and bottom and two lengths of 51.1/2″ for the sides.

Third quilt border

Finally, for the third border I have returned to the 2.1/2″ strips of light blue fabric.  You’ll need two lengths of 51.1/2″ for the top and bottom and two lengths of 55.1/2″ for the sides.

The square and a half quilt top is now complete and ready for layering, quilting and binding.  More details on these steps can be found in the beginner quilting section.

Thanks so much for all your wonderful suggestions for a name for my longarm machine.  It was a real treat to read them and I really appreciate so many of you taking the time to write in with ideas.  I found it extremely difficult to choose, but I have decided to go with Minnie as my name for her.  It works on several levels – trips off the tongue whether I am pleased or annoyed with her, she is definitely not ‘mini’, and it’s a shortening of minion.  I’m still working on the last bit – she is most definitely the boss at the moment.  I have been trying to work with her a little each day and I definitely feel better about her now than I did a week ago.  My movements still seem a little jerky – but I can hardly blame that on her!

About Rose


  1. Hello Rose,

    I did comment on this pattern last Friday as I liked it so much, but it obviously did not arrive. No idea why. Maybe this time it will. I have also left a comment on today’s one (13th), fingers crossed.

    • Hi Jennie. Your comment probably did arrive, but it didn’t appear straight away because I have to moderate each one. I get hundreds of comments every day offering me payday loans or rayban sunglasses or whatever. I daren’t let comments go straight on the website because sometimes they are quite obscene, so they all have to wait for me to check that they are genuine before I release them. Thanks for taking the time to comment.

  2. This is a lovely design Rose, thanks for your inspiration.

  3. Helen warren says:

    Love this quilt Rose. Think I may give that one a go next with some of the fabrics I got from you a few weeks ago. The effect looks complicated but not in reality. Just done a lap quilt full of hst’s they are not complicated and there are several quick ways to do them. Will send a pic once it is done. Glad you and your new toy are becoming more friendly. X

  4. Shirley says:

    LOVE this pattern. Once again you have outdone yourself. I am always loathe to do patterns with hst. I make lots of quilts but so far have managed to steer clear of them but seeing how nice this one is, I think I might take the bull by the horns and have a go. I am so jealous of you – your very own long arm quilter !!! Woweee. What would I give to have one of those. Are you going to quilt this one with Minnie? Cant wait to see the finished project. Bet you cant wait to make loads of “tops” so you can get going on Minnie. Well done.

    • Thanks, Shirley. Yes, you should definitely have a go at half square triangles. You could always make a couple of sample ones first with scrap fabric. I don’t need to make any extra quilt tops for Minnie – I have a room full of quilt tops just crying out to be quilted!

  5. Shelley says:

    Really enjoyed this pattern especially when I could see two blocks, not just one.
    Hopefully, you and Minnie will become friends as I did with my nemesis once upon a time. I made up my mind it would not win, so I talked to it every time I walked into the room, while I was learning to use it, and when I was ready to leave for a bit. Soon my sewing machine became a friend!

    Hello Rose,

    This week’s quilt project is my favourite! Your tutorial is brilliant and I’m so inspired to make this quilt block. I wait each week for your Friday quilting gift and I feel connected to all those who post along with me to your blog. Quilting can be basic or very intricate – and that’s what makes it great! And, those colours you used this week – simply gorgeous. I don’t know how you do this – given the work/time/volume of emails/family/life demands – but keep it up! thank you.


    • Thanks for your kind comments, Jan. I really appreciate getting comments from all round the world – and as you say it’s a great way for quilters to connect as well.

  7. Hi Rose would this be suitable quilt for a beginner like me. Thanks.

    • Hi Janet. I believe this quilt pattern is suitable for a beginner. Just take it gently, one step at a time. Good luck.

  8. Sandra Barnett says:

    Oh Rose,
    I love the quilt so simple only one block that comes out looking like too. Genius! Finished my baby quilt. Will give it August to my brand new granddaughter.
    Think I will make this one next. Right now I want easy.
    Good luck with Minnie, you will come to love her once you conquer her.
    Have a great weekend.

    • Thanks, Sandra. I’m glad you like the quilt pattern. You’ve certainly finished your baby quilt with plenty of time to spare – I wish I was that organised!

  9. Love this block pattern, thanks again for sharing! And Minnie sounds like a winner 🙂

  10. Dear Rose ,
    What a lovely name Minnie for your Long arm, enjoy your course you soon will pick up how it works, enjoy.
    I am really tempted to buy that pattern and Fabric , just what I need to make me do something different . Hope you still have it on offer when I make my mind up.
    Best wishes Rhoda

  11. Rose, This is a beautiful pattern. As usual you do a great job
    with your tutorials.
    Thank you. Best of luck with Minnie.

  12. Cecilia Alcantar says:

    Love it, love it.. it’s a darling pattern. The name that you’ve chosen “Minnie”” is appropo indeed. Never ever will the name sound intimating .(clever).
    You keep on keeping on for the love of quilt making!!!
    Have a good weekend.

    • Thanks, Cecilia. Glad you like the quilt pattern. I wonder when I’ll be able to quilt it with Minnie’s help.

  13. Sandra Woodhead says:

    What a lovely quilt pattern! I’m always slightly nervous with half square triangles, but your clear tutorial is giving me the confidence to tackle this.

    Many thanks again for your lovely tutorials.

  14. Lori M. says:

    Oh the quilt is lovely,,,and I hope Minnie will get over her move in and start living up to her other sister’s name, Maxie, where she will save you all the time needed to quilt, and not be the maximun like her sis….

    • Thanks, Lori. Sadly I have to admit that the problem is with me, not Minnie. I need to be a rocket scientist to get her set up properly – either that or call in a teenager!

  15. Hi Rose,
    This is a great quilt, I like the idea of one block

    • Thanks, Tina. It certainly makes for a quick and easy quilt – and even better when it looks like two blocks.

  16. I love your 1 1/2 block quilt. It’s very clever.

    • Thanks, Pat. I’m always amazed at what can be achieved just by cutting up fabric and then sewing it back together again!

  17. Good job, Rose! I love your quilt. I like the blue/green combination and I especially like the three borders. One of these days I’ll get up the courage to try making a quilt with 1/2 square triangles. I started making another baby crib quilt and it’s turning out pretty good. They are fun because they are fast and very easy to make.
    Glad you’re enjoying your new toy.

    • Oh Claire, you don’t know how pleased I am to hear that you’re making so many quilts – and having fun doing it. Well done!

  18. Brenda German says:

    I love this! Gorgeous, and easy to assemble. And your fabric choices are lovely. I love how you used the lights and darks.

  19. Kathleen says:

    I like this pattern and how it creates the look of two blocks! Love the colors you used as well. I’ve not made a quilt using your tutorials so I have a question. With your suggested cutting measurements, once each piece is sewn, for instance a HST or quarter square triangle, should they come out exact size or do your measurements allow for squaring up each piece? Thank you.

    • Hi Kathleen. My measurements should give the exact size. Occasionally it doesn’t work and I have to (whisper this) tug a bit to get everything to fit. I make so many quilts that I always feel that making hst’s bigger and then trimming then would slow me up enormously.

  20. Susan Margeson says:

    thanks for the lovely pattern. Have fun Minnie, she will serve you well.

    • Thanks, Susan. I’m on a course on Tuesday for new longarm owners, so I hope to become more proficient after that.

  21. Rose, that is an absolutely lovely pattern. Thanks for sharing. I’d love to try this one.

  22. Absolutely lovely block/quilt very do able thank you Rose

    Have fun with Minnie.
