First of all I hope you're feeling better. Summer colds are the pits!
I hear you on feeling guilty. My parents grew up during the Depression and I inherited some of their ways. I dislike wasting food and things like that.
Fabric can get overwhelming though. I get nervous when I have too much in my sewing room so I donate scraps to Good Will or a similar place. So far they take them. I really don't like scraps because when I finish a project I'm sick of the fabrics I used.
I just thought of something- a lot of people on this board like them. Maybe offer some and have them pay postage? It would work out well for both people. Just a thought.
