Great idea, thanks.
It always amazed me when I used to do Craft Fairs that the stuff I put tons of work into never seemed to sell, and the small quick items that were easy to do sold well.
One year I made little children's denim aprons with pockets for crayons, paint brushes, etc, and filled the pockets with inexpensive crayons. They sold like hotcakes, and were so easy to make.
