Mull it Over Monday: Three Top Requirements: when selling art offline

Last Monday I wrote about how finding people who buy art is important if you are selling art.   It might seem like a no-brainer--but making smart choices when it comes to choosing venues for your art can make all the difference.  Here's the three things to look for in offline art venues.

Sometime in the 90's

1) A nice person present and within speaking distance of your art, a person who greets people and is available to chat and make the sale. I had a brief exhibit at a hair salon once. Even though it breaks my rule that forbids showing art in a non-art venue--The salon owner was always there to talk about the work and she was genuinely enthusiastic about it: Thanks to her, sales were made.  Finding people like that is like striking gold.   
2)  A destination that attracts lots of your target traffic: A museum or an art gallery specializing in the type of art you do is ideal! But remember, your target traffic is as unique as your art. I had good sales at the Cleveland Botanical Garden Gallery, but I paint flowers so go figure. Consider the issues and subject matter upon which your art is focused: Who cares about it and where are they? If your art focuses on conservation, find the next green event happening in your city and see if there's an opportunity for you to exhibit there. Well attended public institutions, tradeshows and special themed events in your city are good places to start--depending on your art.

I don't think he was happy with it.

3) TRUST:  When the stars line up and you've found a place that meets your needs:  Do not leave your art there without a written receipt, consignment form or contract.  Maybe they have boiler plate paperwork or maybe you'll have to print out your own.  Cay Lang offers some fantastic resources for paperwork in her book Taking the Leap.  Trust the person/business, if you have to call and get some referrals from fellow artists, do it.
