Something from several years ago that was one of my first woodworking projects. I restored an old table that was dried out and peeling. Sanded down and refinished with a few coats of polyurethane.
I decided several years ago that there was so much wood that I saw in the landfills, that it was possible to use that for most of the projects I do.
1) It saves me a ton of money!
2) In a small way, it helps the environment, less in landfill, fewer trees cut.
I believe that trees are a renewable resource, I am not at all against using non-recycled wood for building, fine furniture, etc. I just feel not abusing the resource is the important part!
