I would be livid! To think that you so graciously gave fabric like that to her, and for it to end up at goodwill, oh, that's just over the top.
I think I would be inclined to send her another email. Ask her how the fabric worked out for her and see what her response to you is. Of course, you probably won't get one.
I would also be interested to know if her notice still appears on Craig's list as well.
