Jay, I think you misunderstood my comment. Mianne bench work dimensions are measured from the center of one leg to the center of the next leg, so when you lay a standard 4x8 sheet of plywood on top of a 4x8 section of bench work, the tops of the legs don’t get covered. This makes it difficult to add a decorative facia to cover the plywood layers and rails for a more professional look. Some add a 1/2” or 3/4” edging strip to fill that gap, others overhang the plywood then add a 3” or 4” facia, a curtain or some other covering. You can’t recess the legs like you could with traditional 1x or 2x framing. Then you could recess the legs 6” or so to avoid bumping them as you walk around the layout. Technically you could do that with Mianne by adding a 6” extension around the perimeter, but that adds quite a bit to the cost.
