I follow ReBuilding Exchange (a great local Chicago resource for reclaimed building supplies & fixtures - love it!) on Facebook & they posted a picture of this sculpture by Vincent Kohler. It is a great visual that explains how a log is cut & planed to create wood ready for building. I found it to be fascinating!
I went into the ReBuilding Exchange last week just to poke around a bit. They have aisles of old doors, reclaimed wood, kitchen cabinets, sinks, toilets, you name it! What I also loved were the carpet tiles. At $2/tile, I was able to put together a 4x6 rug for $12. It was high performance contract carpet, perfect for an entry. I wasn't able to think of a place to use it, so I put it all back...but let this serve as a notice to you if you're in the market!
