I would make as many items in the time available leading up to the craft show. Try to have a wide variety of items in all price ranges for sale. Put one or two of each pattern or style on your display table even if you have multiples of that same item. This could possibly decrease the amount of merchandise that walks off. You could also take pictures of your wares and put them in a binder to show potential customers all the styles and colors you have available. The binder could also be used to keep track of the inventory you have left if you mark it off as you sell them. Make your items stand out from what is available in the stores. Maybe meander instead of doing all grid quilting. Even if you have items left over after the sale its okay because Tennessee seems to have an abundance of festivals and craft fairs. Good luck.
