As a vendor I sold things $15 and under and I did well. And I made sure I had a business card to give them if they wanted something they could call or email. Got good feed back from that. Maybe a quilt is to much at a craft fair, but when they go home the brain is saying I really love that quilt and you just might get an email sale. Years ago doing craft fairs I sold cheap ,never included my time and sold volume. Other crafters couldn't understand how I could make so much money. ( I had a following, they all looked for me. In todays age email these people when your next fair is and directions and you could also built a following. If you look at an item and ask what would I pay for it, add a dollar or two so you can say look I can see you really like it and price is an issue I give to you for and knock of a dollar. Remember everyone loves a BARGAIN! Have a Pad on table and your business cards tell all who come to your booth if they would like to put their email down and you'd let them know date and place of next fair you'll be at. Good Luck you got some good feed back which should help you get started.
