It's always a roll of the dice as to what will sell at craft shows and what will not. Having "donated" hundreds and hundreds of baby quilts, table runners, placemats, etc., in this area I can sell a baby quilt for $35-$40, placemats $25-$30 for a set of 4, and $25-$35 for table runners, generally. Last fall I had my own booth at my church's holiday fair, I sold mostly table runners, some placemats, but surprisingly I sold 11 out of the 14 Bow Tucks bags for $35/each. This year I may not sell as many, but some things I can give as Christmas presents, or set aside for another year. If the church is in an upscale neighborhood, you can probably add $5-$10 each and sell them quickly. Figure out your costs as others have explained below to give you a more accurate pricing range, but a lot really depends on the area of the fair. Good luck. If you make good, quality items, they should sell.
