It is important to understand all of the issues associated with selling at craft fairs before deciding to do so. Cost of Fairs Sales made at craft fairs are retail sales - that is, you receive 100 percent of the selling price. Depending on the fair, you might pay a booth fee or a commission.
Some fairs have both.
Booth fees vary from five to hundreds of dollars, and commissions vary from 5 to 50 percent of all items sold at the fairs and orders taken while at the fair. On top of these fees, some fairs require a jurying or registration fee. In a juried show, participants are asked to submit examples of their work via slides or photographs. A panel of judges then selects the work of craftsmen that best fits into the format of the fair. This ensures that high-quality items are sold at their fair.
