At the PaperCrafts expo, ChiChi had visitors to her booth do the little 2-4-6-8 box in her gallery -
Gallery at Splitcoaststampers - that seemed like a big hit!
There was a CTMH booth that did the little bagalopes, little gift enclosure cards, and something else. They offered a different project every 2 hours, I think. I thought that was a pretty good idea! They had the different projects posted with the times they would do them listed. They charged for the make & take, though.
Good luck!
