I would say thanks but no thanks!!! People are not prepared to pay for your time!! They see something in a shop/market/magazine then decide they know someone who will make it cheaper!!!! She might want you to work in fabrics/colours you don't like which is added stress! Just explain you sew for your own enjoyment and pleasure not for profit!! If you are asking us what we feel you obviously have doubts so go with your gut instinct and say NO!!!!
