I've tried the Leah Day patterns and they drove me crazy using regular copy paper, plus you have to make a hundred copies or so. Not sure I'd have the patience to pull off all the papers once sewn onto a quilt and I'd be aftraid the stitches will pull out and break. Would onion skin papers (Office supply stores or Amazon) work. I do have some Carol Doaks PP foundation papers I've never used. What about them?
