I went to a craft fair last summer and the reversable quilted aprons were selling like crazy. They were priced at $25. I also saw a lot of people buying an over the shoulder, sling like carrier for water bottles. I saw them made from fabric and crocheted with cotton yarn. Try to have a partner with you --- for when you need a break for lunch or the restroom, and to help with setting up and carrying everything. Good luck and have fun! :D
