I like to make purses. I had a gal ask me about my current purse. She loved it. When I said $50 she really backed up. She said, "I can buy purses for much less than that" My reply was, "Well I don't have a sweat shop full of people being paid pennies per hour to make them. Also, I don't like to use cheap fabric." I got the perverbial nose in the air and walk off from her. People think "well you are doing this at home" and you shouldn't be compensated for your time.
I do agree with the husband, the MINIMUM charge for the quilt should be $100 over materials cost. OR you could give her the "friend of a friend of a friend" pricing and charge $150 over materials!
