In doing craft shows the past five years, I have found that small covered notebooks that can be carried in the purse; pins made from soft drink cans which are very colorful; reindeer food packets, treat packets (especially around Halloween and Christmas have been the favorite sellers. Also, pre-decorated 12x12 scrapbook pages. I display one in a 12x12 frame with pictures that can be hung on the wall. Cards seldom sell well but attract attention where you can talk about classes and find interested people to add to your customer list. Make sure to have sign up sheets for upcoming classes.
