I've done a few booths like this. I find if you have an item for under $5.00 you can sell lots and at least pay for the space. I make dish towels out of 'birdseye diaper material' hard to find lately. I then take a strip of fabric, or strip of border print, put it at one end, make sure all sides are dobule hemmed. I sell them for $2.50-$3.00 each depending on venue. I usually make at least two of each fabric design as I quickly learned most people buy 2. good luck, I envy your sunshine
