3/4" x 4' x 8' sheets 2 sided maple plywood $60 x 4
box of 1 1/2" screws $10
wood glue (had some left from other projects)
keep in mind, i had a top notch wood shop avaliable to me. some tools that were essential were an air compressor, pocket screw machine, pocket screw gun, large staple gun, router, orbital sander, and clamps of various sizes...
o yeah, and the stain and finish cost me about $100. you dont have to spend this much on it though.
probably cost me a total of $450
about 22 hrs of labor, including staining and finishing.
