I've been working on my trades for Artfest. I went a little overboard with these miniature booklets. They include 3 tags for note-taking (one for each day of the retreat), and a fourth with a schedule of the evening events. I made the booklets from 12" x 12" double-sided sheets of patterned paper that I bought at Archivers, but I can't remember which brand I used. They aren't exactly original art, but I wanted something springy and colorful.
