When starting out selling crafts, there are some common mistakes people make. The biggest is under pricing work. If you do not pay yourself enough in your pricing, you may find that you are working for pennies an hour. Believe me, it happens too often... Another pitfall to watch for is attending the wrong types of shows. If you are selling low cost products that have mass appeal, then street festivals and flea markets might work for you, but if you are selling high-end one-of-a-kind artwork you should primarily attend fine craft and art shows.
