I once gave a $5 bill to a man who gave me a sob story. We left him off at McDonald's as he had asked and then drove to the stop sign. We had to wait a long time there, and in the rear view mirror I clearly saw him take something black out of his pocket, fiddle around with it a little and then put it back into his pocket. He hadn't gone into the store as he said he would because he was so hungry. I didn't feel badly about that at all. I had given the donation in good faith, and what he does with it is on his conscience. God'll get 'im!
We were always told not to send fancy quilts to charities because they could end up on the black market. I try to use up fabric that has been around a while and I don't want to see it any more. Use sale fabric if you don't have enough at home. Hancocks Fabrics has a blowout every once in a while. Most of these are very good fabric, just prints that didn't sell. I have pruchased whole bolts of some real funny stuff and used it for backs for charity quilts.
You will be rewarded for your work . . . later! Save your anger for something you can do something about.
Peace!
