The May block 
is the 9Patch, obviously so called because 9 patches are sewn together. It’s one of the oldest and best loved blocks in the quilting world as you can make a lot of different patterns using this block. I collected a few possibilities on a Pinterest board – click here to see them.
In my block I combined two 9patches with two plain blocks.
Sewing the 9Patch
For the 9Patches cut 10 squares 2 x 2 inches (= 2½ x 2½ inches including seam allowances) out of fabric 1 and 8 squares the same size from fabric 2.
Join 3 squares: fabric 1 – fabric 2 – fabric 1
Sew 4 rows.
Iron on the backside pressing all seam allowances to the left.
Join 3 squares: fabric 2 – fabric 1 – fabric 2
Sew 2 rows.
Iron on the backside pressing all seam allowances to the right.
To complete the 9Patches sew three rows together. Because you pressed the seam allowances in different directions you can now push the seam allowances together to get a perfect match of the seams.
Cut 2 squares 6 x 6 inches (= 6½ x 6½ inches including seam allowance).
Sew a big square to each 9Patch.
Join the two halves to get the finished block.
