My advice is stop accepting the "gifts" now unless you are prepared to make her a quilt. You are being nice to her when you accept these things, but she may very well be expecting something in return. You can be nice to her in other ways, but you could tell her, in regards to her "gifts", that you have more than you can ever use, and she should give them to others who can use them. I have experienced something like this, and believe me when I say you are better off to find a way to avoid accepting anything more from her. This might not end with you making her a quilt anyway, especially if she is an "odd duck".
