6. Question: Where do I buy wood for the planking?

Answer:  Lumber suppliers and home improvement stores are the obvious answer. Most builders love the challenge of finding the perfect wood for their board and they will search through pallets of wood to find the perfect pieces.  We have found beautiful heart redwood being sold for planter edging in the garden department of Home Depot.  Lumber suppliers like Austin Hardwoods will even cut a custom kit for you.  The assembly manual lists a lot of good sources and

even tells how you can get free wood.
