This sounds like it is where they got the idea that you were just quivering with eagerness to make them other quilts, so let's start with something small and work her up to large ones.

Be kind, be courteous, be friendly, be firm as heck and if you don't want to, the word NO is not too easy to say but necessary with some folks.
