Rubber Door Mat Wall Art (good idea for the metal screen for the air return on the laundry room door)The most frugal decor idea I've ever seen: a vintage iron piece for the wall. Go to the dollar store for an outdoor black rubber door mat. Then spray paint them with Heirloom White from Home Depot. You can take a hand sander to them after they are dry to give them an aged feel.

Faucet handles.... rustic
Penny ball - supposedly repels slugs if you leave it on the ground. Or clean the pennies nice and shiny and use it for garden art.
