They really are easy to do. The one I did was 1 1/2" strips of 8 different fabrics. the strips are sewn into sets and cut 11 3/4" for large triangle and 7 1/2" for small triangle. Hope this info helps but I have been told there are different measurements depending on the pattern. Same design, different names. New Orleans Puzzle, Crazy Eights, Strata Star and probably others I don't know about. Hugs
