You are all making me believe I can do this. Is it better to use Best Press before I cut the squares on the diagonal? It seems that this would be be more effective in preventing stretching than after cutting. It would minimize stretching in cutting and sewing. I know I will have to handle the triangles carefully while sewing to make sure there is no pull to cause stretching. You are all so helpful. Geri B, you were very helpful in helping me visualize the process. Thanks everyone. If anyone has completed this pattern or one like it, I'd like to hear how it turned out. I am expecting it to be time consuming. I have a thing about points. I am OCD about everything matching.
