Thanks everyone for your opinions. It bothers me more because my hubby said on the day she took it, that I'd never get paid for it. She attends the same church as my mom as is an active participant there, so it bothers my mom that she did this. Personally, I was glad to be able to help out someone in need. Red plain flannel isn't exactly something one can find readily locally, I knew I had some, she said she needed some, so guess I could have just kept my mouth shut, or maybe asked her how much would she be prepared to pay for flannel... Lesson learned.
I think I will call and check on her progress and see how things are going. If she brings it up, that's great, if not, well I will let it go. I feel that people have been good to me and it's not like I can't live without this flannel. If she can live with it, so can I.
