Okay! Now I get it! The triangles, pieced or solid, are sewn together in rows, not in 6 sided shapes (geometry is not my strong suit!). But this is not how she (assume a "she") did it.....wonder why?
But it's going to be the way I do it!
Thank you for your help! Maybe the fun of quilting is because they are so often an illusion, and that includes how they are put together.
