I have done craft fairs for over 30yrs. You make a little money but not a lot. People expect tp pay Walmart prices for quilts. You need at least one item that is cheep to make and sells for under $10 that you can sell a lot of. The reason I do them is, I can produce more product than I can give away, It lets me try new patterns, and the satisfaction of making something someone wants to buy. A good ego boost.
