I've got them all pressed and sorted. I sorted out all the solid black and have them set aside. My problem - after looking over the tutorial, this method is too similar to another major project I'm working on right now (basically a lot of strip paper piecing) and I'm looking for something to do when that gets too tedious. But now that I have these all pressed and sorted, I really do want to use them in something . . .
I think I could modify the method and do them without paper, just make angled strips and then sew them into rows with the triangles in between.
