Did you ask for a tax receipt? It's hard to tell from your post if you asked for one, or waited for one to fall into your lap.
I've made a lot of quilts for charity, but never bothered to ask for receipts for tax purposes. I may be wrong, maybe Scissor Queen can clarify this for me, but it just seemed that the tax benefits weren't worth the effort. (Of the receipts, NOT the donations. They're totally worth it!)
