A combination of a crazy 2-week sale at Military Simulations, and the Geek and Sundry: Table Top Youtube channel prompted the build. I've backordered a pile of fun lookin' games.
A quick scaled sketchUp plan to get started. I've bought materials to make padded 90mm x 40mm borders, with cup holders in the corners. :-) 
Laminated board, both sides...it's about "this" big.
Cut-laminated edges are pretty sharp. A router fixes that problem quite neatly. An impossible sanding job otherwise.
**Jumped ahead** I put green felt on one side. It's actually glued on.
The other side is getting a faux leather vinyl covering. I've used this stuff on a few other builds in the past.
Normally I'd just stretch-tack the vinyl down, but I needed neat (visible) edging, so decided to use a spray adhesive on both sides to make the tacking phase a bazillion times easier. 
Spray, roll, burnish. Spray, roll, burnish. Easy peasy.
Fold, tuck, measure, tack. Fold, tuck, measure, tack. Easy peasy.
25 tacks later, one of the short ends is complete.
And before I could finish all four sides, a test game was required!! It may take a while before I get around to the edging, I'm feeling lazy, and the board surfaces are great. :)
