Things I have learned about the art and craft of decoupage over the course of the last few days:
1)
Cardstock works marginally better than I thought it would. By which I mean it is just barely possible to use it, if I tear the stuff into teeny-tiny pieces. If the piece is bigger than a penny, it's too big. I will never buy it on purpose, and will re-double my efforts to not get any by mistake. But, I will use up the package I did buy accidentally.
2) Origami paper works even better than I thought it would. In fact, it may be the ideal paper for decoupage. It's almost as pliable as tissue paper, but not nearly as fragile and prone to tearing when I don't want it to. It also comes in all sorts of pretty colors and prints.
