One of the quickest and least expensive ways to update the look of your kitchen or bathroom is to install new drawer pulls and cabinet knobs. Hardware can also be a way to bring a splash of color without painting entire walls. Here are some gorgeous examples made from materials like recycled glass, cork, and stone.

1 SpectraDecor: SpectraDecor's Luminous and Beach Pebble lines are made from 100% recycled glass in Seattle, Washington. (Luminous contains post-consumer or post-industrial content depending on color, while Beach Pebble is post-consumer content.) The company's Fusion2 line is made from 100% recycled aluminum with environmentally-friendly inlays like cork and shell.

2 Paloma Pottery: Paloma Pottery's door and drawer pulls are made in Ferndale, Washington, from recycled glass jars and bottles fused into pottery.

3 Aurora Glass: The Aurora Glass Foundry's drawer pulls are made from 100% recycled glass. The foundry is owned and operated by the St. Vincent de Paul Society of Lane County, Oregon, and all profits assist homeless and low-income people through emergency services, housing, jobs, training, other charitable endeavors.

4 Serena: Serena's Sea Stone knobs and pulls are handmade in New Hampshire using hand-gathered, ocean-smoothed stones.

5 VivaTerra: VivaTerra's recycled glass knobs are handmade by a family-run studio.
