Found these guys through their Craigslist ad. I was searching for lumber, but found so much more. They reclaim materials from stage and movie productions and keep it out of landfills by offering it at low prices to us in the Philly area. They have a little bit of everything that is involved in arts/crafts/light construction. Think about everything that goes into completing a movie set! Props, lighting, staging, wardrobe. They have bits and bobs of nearly any supply you could need for a DIY project.
They are easy to get to here in Fishtown and are open easy hours. We got some door hardware, fabrics and foam for reupholstering chairs, some air dried poplar for woodworking projects, pens, carving tools, flooring, and a light fixture.
Go if you need something for your current DIY project, but don't be surprised when you find materials and inspiration for five more. Go often, the supplies are always changing.
