I stained the table and benches dark to match our cabinets.
I created matching benches based loosely on the table plans. The benches are made of 2x6 for the top and breadboards. I left out the stretcher on the benches as the 2x4 and 4x4 frame structure was more than sufficient.
The table was finished with a paste wax rather than poly. This gives it a smooth, water resistant finish without being overly glossy. The goal with this style, after all, is to make it look somewhat old. The wax does a great job.
