*Your booth is your store and you are the owner/manager/artist/ruler - so be professional.
*Open early and close late. (Even if you haven't seen a single human since 2pm...YOU NEVER EVER KNOW....)
*Follow every rule that the event has...to the letter. Have questions? Find the organizer.
*No complaining, bellyaching, or backbiting in your booth. AT ALL.
*No complaining, bellyaching, or backbiting in another vendor's booth. AT ALL.
*If you must vent then find a neutral space away from it all.
*If you are visiting with another vendor, be aware when potential customers walk into the space. Back off. The event is about connecting with customers and selling.
*Raise your tables. This isn't the 1960s and we are not hippies.
*Use lighting. Regardless of your product. Light it up.
*Ignore the strange comments that passers-by make. They aren't your customer anyway.
*Do you know who your customer is? Write a profile of your perfect customers. Review this profile when it's slow.
*Keep a mirror handy to make sure spinach isn't stuck in your teeth...or other such debris!
*Stay out of vendor gossip. Some of it can get so far off base it's ridiculous.
*Don't worry about that other jeweler, photographer, fabric artist in the show. You have your unique look and customer and s/he has their own.
*Stop talking about the horrible economy. There are individuals who WANT to spend money on original work. There is plenty of money.
*Make a quality product with a guarantee.
*Customer service is EVERYTHING...
*Smile (worth repeating)
*Ditch the "victim/artist" mode.
*Artists are visionaries and innovators. That is a powerful position.
*Offer the world something irresistible.
