Set your booth in a U-shape or L-shape with your tables, quilt racks, etc. Gets people to walk IN to your booth and they take more time to look at things. If you just have your table across the front, they only scan as they walk by and they don't really SEE your inventory. If tax is included in your price, have a sign saying so. If you are going to take special orders, be prepared with prices listed in writing.
