I bought the book a while back, but haven't tried it yet. I do plan to. The quilt I had in mind at the time was the french braid in my avatar. I was concerned it might have an effect with the bias since it wasn't laying as flat as I liked once pieced. So I also chickened out. :) I did try out samples of each method and liked the one where you sandwich it, then fold the top/back out of the way and cut off a section of the batting (to replace later). I liked the results best that way.
