There is a wonderful article on valuing your work here:

My sister sells things at a craft market twice a year, and she usually sells out while others around her are not selling a thing. She makes beautiful scrap potholders, microwave bowl holders, tissue cases, and small pouches. I don't know how she prices them, but none of her items look home made; rather, they look hand made. Quality always counts when you are selling anything.
