.... because it is a beautiful block but it is a beast to make. I didn't have as many problems with the stretching thanks to the advice from others, but I had to rip out several pieces because I had sewn them backwards. Then when I put the big triangles on I lost quite a few points. I think Rebecca has the right idea with this one and that is to paper piece it. I may give it a try at some point since I really would like to learn paper piecing and I like this design. It will have to wait though since I've got to get back to my other projects.
