Like a lot of other folks, I have lots of signs I've made that I'd like to display in the shop.
My shop is metal skinned, so two or four earth magnets on the back of the signs would allow them to be displayed pretty well.
I'm looking at some on EBAY, like these:

My question is, how do I know the holding weight of these things? I'm sure they'd hold a small 8x12 sign made out of cedar, but how big of a carving can I count on them holding?
