Here’s something I did up a few years ago and am giving it a rerun here:
Every so often in the mailbox in our former neighborhood would appear one of those booklets that’s 60 or so pages of “Send me your dollars and god will send you dollars/make you well” etc. A prayer cloth (1 by 1 inch square of white cloth) was sometimes enclosed. I’m sorry I ditched the booklets when we moved because we don’t get them here. The graphic itself is from one of those booklets.
