Pros : This paper is great! It doesn't turn to dust, so clean-up is a breeze. I was able to get two full-fuse firings out of one piece...so that's like getting two sheets for the price of one!
Cons : As another reviewer mentioned, if you plan to reuse the paper, be sure to let the glass come down to room temperature before removing the piece from the paper (or at least give it the nudge test...if it moves, you are good to go, if not, let it continue to cool), otherwise the paper will stick to your project. If this happens, it is still easy to remove with some water, but you won't be able to reuse it.
