I'm doing a demo on half-square triangles at our guild show this weekend and was asked to supply a handout for it. My favorite way is using Thangles, or other paper sheets like that, so I'll be showing some of them. Have found info and tutes for making them other ways like the diagonal cross on square sandwich, etc., but no simple sheets that I can have copied to bring along. Does anyone know of a source of something like that? Thank you for any ideas!
