Lots of cash or zero balance credit card. I have been to Paducah 4x and love it. I went the first time and good shoes are of course an absolute must, as is a small digital camera. I like carrying a tote that is comfortable to carry around. Also I realized that it is best to have a list of what I want to buy. The second year I focused on brown fabric, the third year on batiks. The 4th year I wanted to buy some small lap size quilt packs. I also take some munchies for the bus trip and a good book, sometimes a small lap robe for keeping the chill off when I doze. Be sure and have a good attitude and a tactful mouth when discussing other people's quilts. They may be within listening distance !
