Well I would tell her that it cost $$ to make quilts. You do not mind putting in the labor but you need her to give you $$ for the fabric and batting. If she refuses then tell her it is impossible to do it. She needs to understand that the first one was a gift because you wished to give it to the person you made it for. That does not mean you have to make all quilts for free. Honesty is the best policy maybe she thinks you do this for everyone for free. Let her know how you feel.
