Hi Tidbits:
Are you a demo? If so, lauraos is right, you can't sell current catalogs AND your handmade crafts at the same time. You can either represent yourself as a crafter, or as a demonstrator, but not both at the same time. And if you sell cards/crafts, you must attach a stamp that satisfies the Angel Policy (like the personalized "handstamped by" stamps that they sell in the catalog) because the images are copyrighted.
Demo Support is VERY STRICT about what they allow you to do at craft fairs!
When in doubt, check your demo manual or call DS. 1-800-STAMP-UP
Good luck at the fair, hope you sell lots of goodies!
