A friend of mine does craft shows but not alone since mother nature calls at the worst times. I helped her with a couple and people really enjoy the "5 finger" discount. She's been doing it for a number of years. She always tries to add a couple items different to see what kind of response. She made some Christmas spiders with the history of them attached. She gets on a list and keeps track of the different events. She also had a full time job and a very supportive family since all benefitted. Her 2 girls did face-painting and made money also. She kept an eye on the weather predictions. She also check to make sure she could get a refund if an emergency came up or an event was cancelled since scheduling for a later date sometimes messed up her schedule.
