Sudoku Quilt Pattern

Sudoku quilt pattern

The sudoku quilt pattern can be very complicated or very simple – so you can guess which option I chose!  I have seen sudoku quilts with a complete quilt block for each number, but I have just used a square of fabric for each number.  It was a lot more easy than I had expected to come up with a pattern.

If you haven’t come across sudoku before, there are nine numbers in each block and nine blocks altogether.  The idea is that each number appears only once in each column and in each row.  The sudoku quilt does this by using nine different fabrics.  Each block has one square of each of the nine fabrics and they are arranged differently in each block to make sure that each fabric appears only once in each row and once in each column.  That means that the actual construction of the quilt is simple – it’s just a series of nine patch blocks – provided that you have a sudoku quilt pattern to follow.

I have used 4.1/2″ squares because that way you can cut all nine squares required in each colour from one width of fabric.  I have chosen the nine fabrics fairly randomly.  They just need to be bright and have a strong contrast between them.  I have used 1.1/2″ white sashing between the squares in each block and 2.1/2″ black sashing between the quilt blocks.

The quilt measures 56″ square.  I have used one 4.1/2″ strip cut across the width of each of nine fabrics, about 1.1/4 yards of white fabric and 3/4 yard of black fabric.

Cutting requirements for the sudoku quilt pattern

4.1/2″ squares:  nine each of nine different fabrics

1.1/2″ strips of white fabric:  fifty four 4.1/2″ long, thirty six 14.1/2″ long, eighteen 16.1/2″ long

2.1/2″ strips of black fabric:  six 16.1/2″ long, four 52.1/2″ long, two 56.1/2″ long

You may be able to read enough of the pattern from this photo, but if not you can download the sudoku quilt pattern here.  Each set of nine figures relates to one individual block.  It is important to follow the layout for each block and for the way that the blocks are laid out.  You also need to be sure that each block is the right way up when you sew it into the quilt, so I always pin a label showing the block number to each block as I make it.

Making the individual sudoku quilt blocks

Cut nine 4.1/2″ squares of each fabric and label them.  It is crucial that you can keep track of which fabric represents which number, so the simplest way is to lay all the squares of one fabric on a sheet of paper with a number clearly marked on the paper.

For each sudoku quilt block, lay the squares out in three rows of three using the pattern to show you which colour to place where.

Sew the squares together across each row

Place a 4.1/2″ white sashing strip between each square across the rows and a 14.1/2″ white sashing strip between each row.  At this stage you don’t want the white sashing around the edges of the block – it is easier to sew that on later.

Add sashing around each block

Sew the squares together across each row and then sew the rows to each other with the sashing between them.

When the rows have been sewn together, sew a 14.1/2″ sashing strip to the top and bottom of the block and a 16.1/2″ strip to each side.

Make nine of these blocks, using the sudoku quilt pattern to change the placement of the squares within each block.

Assembling the sudoku quilt pattern

Sew the blocks together in three rows of three.  In order to separate the blocks completely from each other, I have used black 2.1/2″ strips of sashing to join the blocks and the rows.

Sew a 14.1/2″ strip of black between the blocks.  You will need two strips of sashing for three blocks, so there is no sashing on the edges of the rows.

Cut four 52.1/2″ lengths of black sashing to sew between the rows of blocks and also at the top and the bottom of the sudoku quilt pattern.

Finally sew a 56.1/2″ length of black to each side of the quilt.

That completes the sudoku quilt pattern.  It is now ready for layering, quilting and binding.  Full details of these steps can be found in the quilting for beginners page.

    Rose, I love all your quilts and so appreciate you taking the time to offer the patterns and a tutorial each week. Sudoku is a favorite game of mine and to make your quilt will be such a pleasure.

    • Thanks for your kind remarks, Nancy. I envisaged people having a bit of fun checking that the quilt was genuinely sudoku.

  2. Another lovely quilt Rose.

  3. I love your website but have never been inspired to actually make one of your quilts until now. My dad is a 94 year old Sudoku addict. This will make a fabulous lap quilt for him. Thank you so much.

  4. As s sudoku fan this is a great quilt for me and will go on my list of ‘to do’ projects, thank you for the inspiration.

  5. Sandra Barnett says:

    Great quilt. You explained it very well. I have tried to do sudkou but always ended up with the wrong numbers in the wrong row. You make it look so easy. I think I will save this for another time when I don’t feel too pressured. Baby quilt almost done. Decided to put prarie points for the binding. Coming out nice. You are teaching me a lot.
    Have a great weekend. I know I’ll be sewing.

    • Hi Sandra. I think that having a clear pattern and checking yourself each step of the way is the answer. Prairie points sound great for your baby quilt.

  6. So clever Rose yet another winner. I love this one.

  7. Thank you , this looks like a very fun one .

  8. sue spicer says:

    Just love the simplicity of this design, but all the possible colours would be wonderful to contemplate – inspirational! Thanks for your generosity in providing us with patterns every week.

    • Thanks, Sue. It’s also the sort of pattern that would keep a teenager or child amused while they checked that you hadn’t got a colour appearing more than once in each row!

  9. Hi Rose,
    What a beautiful quilt! The blocks look like window panes. I would have a problem cutting the fabric because I never cut straight. I use 2 rulers to square up the fabric but something always goes wrong and I end up with wonky strips. I am now in the process of making a Rail Fence quilt for my niece. I’ve had to unpick rows because so many of the blocks were out of whack. I also ran into trouble sewing in the ditch with the baby quilt.

    • Hi Claire. I hope you get the rail fence sorted. I find cutting so much quicker and easier with a rotary cutter, mat and ruler. Hope you get the baby quilt finished.

  10. Carol Tambourine says:

    I love this. It is gorgeous!

  11. Another one to add to my wish list 😉

  12. Beautiful
    Just too good and easy
    Can you suggest a quilt with mens ties
    Thl you

    Thanks so much for doing this quilt. I have a lot of friends that do Sudoku and I’m sure that I will be doing this for at least one or two. I can see that this would be easy to adjust to different size squares, etc. I was thinking of using a charm pack for this. Slightly larger than your squares but then I’m lazy and they would be precut. 🙂
