Last month I participated in two swaps hosted by Amber Dawn of Inventive Soul. One swap was a fabric/fiber charm swap and the other swap was for book charms. While the fabric charm swap was challenging, the book charm swap was a bit more challenging (and rewarding.) If you have ever tried to make a book smaller than 1.5 inches, then you know what I mean. Here are photos of the charms that I received (mine are in there too.)
If you are interested in joining a charm swap, I recommend checking out the International Artistic Charms Exchange group. I have participated in several swaps with this group and have never been dissapointed.
