The simple answer is: whatever the market will bear in your area. Think of craft sales you have gone to in your area. Talk to others who are in the sale. In my part of the world, stuff has to be cheap,cheap, cheap to sell. Unless you have something truly unique that will be "worth" it to buyers, you need to price for your market.
The last craft fair I visited, there were table toppers and pot holders and potato bags and purses and small quilted items all over the place (a large annual fair). Therefore, prices were in the basement.
