I quit sewing for people for just this reason and the fact that the price agreed on was never what they wanted to pay after the goods were done. I made a cute costume for one person for her little girl and she said "oh, the money was in the bag with the fabric" Not!! And another time made a vampire cape for one of the girls I worked with and she paid me half and said can I give you the rest payday? Of course payday never came. So now I just say NO and back to my quilting. So.. I guess the thing is...Just say NO!!!
