I've always used wonder-under. and last time I used itfound it a bit difficult to pull off when I wanted it to, and it came off the paper before I wanted it too - or when trying to peel it off the paper not at all... last time I went to buy some they didnt have any, so I bought heat and bond lite. It's much easier to peel off, and doesn't release from the paper too soon, but has a much stiffer finish. I'm undecided which one I prefer.
