I travel across Canada attending shows each year and I'll be opening up more shows to attend in the USA next year (2012).
Because I'm a steampunk artist, I have had much luck transferring between different types of shows (anime,comic,steampunk,general,etc).Thinking bout the type of show you would like to go to, where it is, how much it will cost to get there and how much merchanidse you'll need to have with you to cover those costs is important and helps avoid poorly fitted shows to your work. KNowing your target audience is also important to keep in mind and thinking about what they might like (as well as yourself) is important to the overall enjoyment of the convention experience.
Somethings I picked up on along the way that I wish I knew when I started:
~Have change. Lots of 1's, 5's and 10's.
~Price evenly and if you can, in whole amounts. Instead of $19.99, a simple $20.00 will do; Does something cost $22.00? Mark it up to $25.00 or down to $20.00
~Have a reciept book.
~Have bags
~Have a ledger of your merchandise so you can check it off as it sells.
~Have tape,scissors ,wire,pens/pencils and extra priceing tags handy.
~Have an extra table cloth to cover your work at the end of the day.
~Have scrap paper handy to jote ideas down
~Always have buisness cards.
~Have some custom order forms handy. A page to write contact info, payment ype, description etc will help you not only look more professional but will keep you organized too.
~Include a 5% (or more) convention fee on top of your average price to help cover costs like hotel, food and travel.
~Have signs that mention you do custom work, do/dont offer refunds, if tax is included in all prices and if things can/cannot be replaced or repaired if damaged.
Some extras that I consider at each show:
~Type of packaging. (Clear bags,paperwrap, bags with bows, boxes, etc.)
~Do I include a thankyou note? I include one if someone spends over $150.00 at my table
~Do I offer a free repair during the convention? I do because I like doing it.
~Should I offer an item to compliment a purchase. I offer free earrings for jewelry purchases over $100.00.
~Should I make something new to debut at my table? I like to do this at major shows that attract over a certain number of attendees.
Hope this info helps and if anyone has questions about what I wrote, I'd be happy to chat ^.^
