I have a hanging ceramic trivet which looks like a DWR quilt on the front. It is about 7" square, and on the back is a thick piece of black cardboard which looks like the back of a picture frame, with a sturdy triangular metal hook recessed into the black backing. If I recall, it was $10 (don't know how I know that, it was a gift---must have seen it for sale on the computer at some point), which I think is a reasonable price for one. I'd have bought it.
What is SGW?
