Years ago, we scavenged around and collected old cast iron register grates from buildings being torn down or remodeled. I wish I had "before" pics because they were in sad shape. We have been cleaning them up this week. The collection of four reminds me of quilt blocks, they are at our door that leads from the kitchen to the deck. The bigger one is at the garage side door. We still have an even bigger one that we are afraid to hang, so have decided to make a table out of it. It was in the floor of the viewing room of a funeral home. I'll post pics later when we get it done.
Didn't cost a thing, except for some black spray paint...........I love them.
