I joined an ATC swap through the group and the theme was pink, purple, stamped (in pink, purple, black or gold) and the ATC had to have a puzzle piece on it somewhere. Here is the ATC I created ... it's been so long since I've made one, it felt a little alien. The puzzle piece is embossing opals ... I'd bought them at a craft show years and years ago and this is the first time I'd used them.
