I would say the indoor show, but then I melt in the sun about the same time my candles do even with a canopy. No one wants to buy candles from the red head who looks like she is going to faint in the heat. I know here in Iowa the weather has been going from one extreme to the other lately. With an indoor show people might be willing to hang around your table and give you some feedback if they aren't worrying about the weather. Even if you have been doing shows for awhile feedback is always nice to give you ideas on how to change things up for next time. Best of luck either way. Let everyone know how things go for you. I just thought of another idea. Is is possible for you to do both shows? If you have a spouse or family member that could do one for you. It can be a headache to have enough product for two shows, but it would give you a good comparison. HTH, Kim
