Thks Chester. I just did a small experiment with a sample Dresden plate. I sewed the plate wrong side up onto a poplin. I trimmed away the excess around the plate, and flip it back inside out. Then I snipped, poked and pressed the petals. Then I trimmed away the excess poplin in the center. Did I do right?
If what I've done is correct, this method is fairly straightforward. The only flip side I see is the extra bulk at the edge of the petals, where the poplin is.
