Most of the materials used in my creations are from recycled or natural resources. A lot of the wood products come from discarded pallets, dead tree limbs, replaced cedar fences and redwood decks. The paints I use are leftover from other projects or mis-tints from Home Depot. The glass is from windows I have replaced from over the years. Most of the metal comes from a local scrap yard. The lighting comes from recycled lamps I take apart and reassemble to fit what I need. Roofing comes from recycled redwood or old corrugated roofing. Bricks are from demoed buildings. The only new material I might use would be the plywood core and light bulbs. I am in the process of using led lighting.
Some items also come from my visits to the local thrift stores but quite frankly I find a lot of cool stuff walking around on the side of the road!
