I often get asked about different sized squares for quilt blocks and so I have made this small quilt as an example of how many different ways there are of making one quilt block. My starting point for this was a 12.1/2″ square of fabric, shown in the middle of the top row.
Using smaller squares for the quilt block
The second block that I made used four 6.1/2″ squares. These are sewn together in two pairs and then the pairs are sewn together to create a four patch unit. This is also 12.1/2″ square, so can be used with the 12.1/2″ fabric square.
The next option to consider is 4.1/2″ squares. For this option you need to cut nine squares and sew them together in three rows of three.
With 3.1/2″ squares you would need sixteen squares placed in four rows of four squares.
The final option that I made was using 2.1/2″ squares. For this you need thirty six squares laid out in six rows of six squares. One further option would be 1.1/2″ squares. For this you would need one hundred and forty four squares laid out in twelve rows of twelve squares.
I have shown the options here for making a 12″ quilt block. The sizes of squares that can be used are those that are factors of twelve: two, three, four and six. If you wanted to look at the options for a 15″ block, you would need to choose from three and five only: twenty five 3.1/2″ squares or nine 5.1/2″ squares.
Add sashing to the quilt blocks
Of course you will have noticed that I have made five quilt blocks above but I need six in order to be able to sew them all together, so I made one further block using two strips 6.1/2″ by 12.1/2″ sewn together. The blocks can now be sewn together in pairs. Cut three 2″ black strips 12.1/2″ long and sew one block to either side of these strips.
Cut four 2″ black strips 26″ long and use them to sew the pairs of blocks together. Sew one strip at the top and the bottom of the pairs of quilt blocks and then sew a 2″ by 42.1/2″ strip of black fabric down each side.
I hope that this will help you decide on quilt blocks, particularly when you want to use different squares within the same quilt block size.
