Need a mathematical genius
I purchased the pattern "Poinsettia Stars" that was pictured on the front of Keepsake Catalog a month ago. It is made entirely of HST. Large ones were to be cut 4 7/8 and small ones 2 7/8. I decided to make it easy on myself and cut them 5" squares and 3 " squares. The first block did not match. The second block I was very careful to cut and make the 1/4" seam. Still do not match. Can anyone tell me why?
