If you research this in the search function for this board it has been discussed many times here. There is so much to take into consideration. What the prices are that people in your area are willing to pay, do you do a "deal" for family/friends, is this person really understanding of the costs and time that go into making a quilt and willing to pay for your time??? There is more that has been brought up here, too. It is a really hard question to answer.
