I agree with everyone else that $50 is a lot less than you should ask for. Use Feline Fanatic's figures and ask for an even $90. Since you didn't have anything in writing, use that as a starting point, then negotiate with her for a lesser figure, but I wouldn't go below $75. Also, don't give her the quilt until she pays you the money! That was a "learning experience" for me, and that was with a friend.
