Very straightforward build. Lowes didn't have many 2x4's that didn't have some sort of warp or bend in them so the bottom shelf had to be trimmed slightly to fit.
There is a sweet spot with the vinegar/steel wool that takes some mixing and testing to find. To strong a solution and the wood turns nice and brown to weak and it's a hardly noticeable light grey. My advice is get a strong 3-4 day old solution and mix 50/50 with vinegar and test on scrap, wait and hour or so to dry and adjust the mix from there until you love it.
I finished with minwax polishing wax.
