Before: Broken doorknobs, After: Patio flooring
Doorknobs, salvaged steel discs, and a stovetop burner make up this cobblestone-esque patio floor. The knobs' chrome and brass
finishes brighten the shady patch of designer Matthew Levesque's (matthewlevesque.com) patio. And, set in soil, the knobs are surprisingly stable.
