I realize that I didn't post any rules on how to trade. Just post in the comments of the person whose work you want. I guess the only rule is to have something posted for them to pick from.
I sat down this morning and made 5 scrap postcards. I did trim the scraps when necessary to fit the collage, and even though some may be cut neatly, all the pieces (except for the postcard backing) came from my many scrap bins.
