This one turned out a little wonky but almost 200 blocks in I've realized that remaking all the wonky ones would be an impossible task. Wonky it is.
Print or trace the block diagram onto foundation paper, number and cut out as in the photo.
Cut the unnumbered sections out of main block fabric. Don't forget the seam allowances.
Out of background fabric, cut 2 squares 2" x 2" and cut each in half on the diagonal.
