That is the way the paper piecing does HST. I have Triangulations, but there are freebies online. You pick a size, print however many pages you need, lay it on your fabric - sizes are different because of hst sizes. Some you get more of. I love, love doing hst this way. Always right on the money. Sew on the printed lines - I use doodle pads from the dollar store - paper comes right off.
