I love that CD! ❤️ I almost always use Triangulations for HSTs and QSTs - so precise! Triangles used to be my nemesis because of the bias, but foundation paper solves that. I hope you'll love it, too.
I just finished a top made of 4,608 HSTs - I used Edyta Sitar's foundation papers because they're longer and they fit onto the long edge of fat quarters, but it's the same idea. There's a picture of my quilt in my photos - it's called "Cherry Cordials"
HSTs don't scare me any more! Have fun with it! 👍
