I've worked craft shows for a number of years. DISPLAY, is very big. No matter what your price, color, etc., is if not displayed well it wont sell well. Your daughter is doing a flower/gift shop, so make sure your items are ready to go now. It's nice that you can personalize items, but people are not always able to wait for you to deliver something that has been personalized. If you have items marked "Can Be Personalized" or "Custom Orders Gladly Taken - with deposit", this will help with future sales. I have also found that having items in colors or prints for special dates (Christmas, Thanksgiving, Easter, New Baby, Wedding, etc.), can also help with last minute sales. Good luck to both you and your daughter.
