I've made 12 little blocks in the last 2 days. That's my excuse.
Print or trace the block diagram onto foundation paper, number and cut out the center sections as below.
Out of background fabric, cut
2 pieces 1 1/4" x 3 1/2"
2 pieces 1 1/4" x 5"
Sew the short background fabric strips to the sides and then the longer ones to the top of the block.
