I started with the intentions of making the exact rustic X console shelf, but when I was looking at all the brag posts, I found one that had the two tone color. The individual used doug fir and only stained the shelves. Once I saw that, I knew what I wanted to do.
I purchased all doug fir 2x6s and 2x4s and ripped down the 2x4s. Built the same way, except when I was done I like the way it looked without the Xs, so I decided to keep it that way. Once thing I'm very glad I did was stain the shelves prior to building the shelf. I did all of my cuts, drilled all my PHs, sanded my shelf pieces, assembled my top, and stained the top and shelves. Once that was done I sanded all of the other pieces and started buliding the frames. When it came time to install the shelves, they were dry and it worked perfect.
After it was all built, I used a varathane satin clear coat over everything. The stain used was Minwax Espresso, 1 coat, let sit for no more than 3 minutes (just the time it took to brush it on).
