Lynn, I did make a case for mine because the destination form indicated one was needed. Labels, and now cases, are the two aspects of quiltmaking I like the least. I did request a receipt and enclosed a self-addressed stamped envelope for the chaplain to return to me but after two weeks, I have received nothing. My mail confirmation from the post office confirming their receipt is the only documentation I have for tax purposes, which does not carry the same weight as an official receipt. Maybe I'll still get it.
