I thought I would share with you all some of my tips for craft shows based on my experience. I have done a 'few' shows and learned some things along the way. Besides the obvious things like wearing sun screen, bringing bags, change, pens and paper, business cards, etc...
This may seem a bit off, but don't expect to make a lot of money. If the show is slow or people are just browsing, then it won't be a big disappointment if you don't make what you expected.
Plan your table display ahead of time. Match your tablecloth and displays, especially during holidays. It really looks nice.
Don't scramble to make things for the show at the last minute. Way too stressful.
Pack up your car with your stuff the night before the show. This saves a lot of time and stress the morning of the show.
Write down all of the inventory you plan to take to the show.
Write down what you sell.
Make sure everything is clearly priced. I find it frustrating when something I am interested in has no price and the seller is busy with someone else. Lost sale.
Bring a project to work on, if possible. People will take an interest.
Bring your own lunch and drinks. Food at shows tend to be pricey.
Bring a friend, spouse, an older child. Helps to have someone watch your table during bathroom breaks. My 11 year old daughter loves to come to shows with me and she is quite the sales lady.
Smile and have fun even if you aren't selling anything. If you looked pissed off, people will see and feel your vibes!
