I've been wanting to make these for a while, and now I finally got around to it! These are styled the same way as the charm books, just downsized. They're about 1.5x2cm or a little over a .5x3/4 of an inch. Sterling silver French wire, 16-page accordion, glass bead accent.
This pair is made from several Japanese papers, and is currently the only pair, but I'm looking forward to more. After I ironed out a few issues they were very fun to make.
