This is the coffee table I built my girlfriend. It took less than a couple hours to build but weeks upon weeks to paint because of rain and work.
The lumber I used was Poplar legs and sides with a Birch plywood and poplar banding. The pain was three coats of Plymouth Blue Oil base. The legs are 2×2 the sides are 1×4 and the top is 3/4 birch with 1×2 poplar banding.
I would say cost was around 75.00 for materials and paint.
2 hrs to build weeks upon weeks to finish because of weather and work.
The original plans had drawers and ws longer, she chose to have it built simple.
Poplar legs and sides with Birch plywood top with Poplar banding.
3 coats of oil base paint Plymouth Blue. I think I might put a fourth coat on the top.
