I'm going to be vending at a show for my first time in April. I'm looking for some advice and ideas on what to have that I might not have thought about. Here's a first very rough draft list I started working on.

Show supplies;

Snakes
Cases
Bedding for cases
Locks for cases
Business cards
Table skirt
Letters to put on skirt
Banner with name
Lights
Paper towels
Hand disinfectant
Fluorescent dry erase pens
Deli cups
Receipt book
Money box
Change
Laptop with pictures
