This wheelbarrow full of wood scraps is where I started this project. A friend of mine works for a company that does much larger wood projects. He messaged me one day to say that they were throwing out a bunch of offcuts and I was welcome to come and pick through them. Needless to say, I wasn't too discriminating, I backed up my truck to their loading dock and started tossing in every scrap of wood I could get my grubby hands on.
I am definitely not too proud to dumpster dive. Getting all the wood for free really brought down the cost of this project. I spent just a hair under $100 dollars to get it all done.
