You don't need to do that. The template that rippled was the long narrow one, and I was able to work it out to mark with the sharpie. same with the Dresden. I just played with it until I had what I think is an accurate copy. I plan to purchse the e-book, one of these days, so if I didn't do a good job, I'll copy from the book template. My envelope got left out in the hot sun( car window) maybe that is what caused it. It was just those two.
