For my variation on the wrapper bracelet I used some Cadbury Roses wrappers from a box of chocolates I was lucky enough to receive for my birthday.
They are a little harder to fold than paper wrappers but I found if I push hard enough, keep holding it in shape as I fold, and keep my pre-weave collection under a book, iPhone or another flat object; they stay in a nice shape for weaving.
At one point I started trimming some of the wrappers that were a bit bigger so that they'd still weave nicely. I warn you that if you do this you should make sure they are cut to the exact same size and no smaller or you'll have to trim all of the ones after that even smaller like I did.
One box made just enough to go around my wrist, I used some of my trimmings as a tie to hold it on.
