The domestic violence shelter near me is always soliciting donations of household goods. I know when you say "charity quilting" most people think blankets, but I am thinking I'll make up a batch of potholders for them.
I'm going to call first (some other day; I called the office today and I think they're closed because of the weather) to make sure they really would need/use them, but it seems like something that would be useful, and I have a TON of scraps I could use for this, both fabric and batting.
