I had blue cut birch plywood for me so I could get it home in my car. I sanded it really well, using several grades of sandpaper, I stained it with kona colored stain and put it together very easily. The only trouble I had was when my daughter and I brought it from the garage into the house because it's big, awkward and heavy. Thanks to TDC for posting these plans. Get building...you won't be sorry.
$120.00 for screws, wood and stain.
15-20 hours? I'm not sure, I work on stuff when I can...and I'm slow and my garage is very disorganized which slows me down even more.
birch plywood - 2 sheets
kona stain - it's really dark - love it
