Curtian Rod Finials - good as Rebar Toppers

While trying to make some tippy pots, (one of the swaps I'm in, the swappers have made some neat tippy pots) and I am trying to make mine, but this wind doesn't stop blowing dirt..

Anyway, I found these at the thriftstore, and I know they come in many colors, or you can spray the rebar and the finial the same color... you can really use them in any thing that has a bar or wrought iron..
