I've sold a few quilts.. the latest one being to a friend at work.. she saw the top and said that's mine..name your price. (it's a lap quilt) I said $250. and she said.. I thought it would be more. and I told her it was because she is a friend she's getting a break. Otherwise I have no problem just saying NO..
Had someone want me to put a new zipper in her wedding dress the other day.. long story, but her MIL to be broke the zipper. I said.. yes I sew clothes but only for myself, and NO I won't replace the zipper.. that's a pain in the a** and I no longer subject myself to that torture. Blunt yes.. but also honest. I suggested she find a professional seamstress and send MIL to be the bill.
