This is one of my favorites.
cut one square 7 1/4" from the background fabric
cut in half on the diagonal twice, to make 4 quarter square triangles
cut one square 4 1/4" from the background fabric
cut in half on the diagonal twice, to make 4 quarter square triangles
cut 4 squares 3 1/2" from the background fabric
cut 2 squares 3 7/8" from the background fabric
cut the (3 7/8") squares in half on the diagonal once to make 4 half square triangles
cut one square 4 1/4" from a dark fabric
cut in half on the diagonal twice, to make 4 quarter square triangles
cut 4 squares 3 7/8" from the same dark fabric
cut the squares in half on the diagonal once to make 8 half square triangles
layout as shown
I pressed these seams open to reduce bulk in the center
trim the tails here, if desired
Once the block is sewn together, square up to 12.5".
Thanks for quilting along with me!
