I just completed my gaming table and Endor mat and I'd thought I'd share the process/results for anyone who might find it helpful or inspiring. I live in a small apartment so my main priority is storage space. I also aimed to construct it with affordable components from the hardware store.
The table is foldable and 6'x30''. I put three 2'x4' sheets of mdf on top to give myself the 6'x'4 playing space.
I made the gaming mat by first covering the boards in a tarp and then clamping a painter's drop cloth on top. I then used roughly 11 tubes of cheap acrylic caulking to cover the cloth and let that dry.
Following that I glued down lots of sand. In hindsight, I should of painted the caulking first with the base mud color but it didn't make a huge difference on the finished product. After the glue was dried, I painted it with a dark brown and sparingly spray painted it with earth tones to give it some more tonal depth. Then I used watered down Elmers glue to apply flock to it , using Woodland Scenic's fine turf weeds, green blend, burnt grass, and yellow grass colors in that order. Once it was all finished I cut the mat away from the extra cloth. Now I store it rolled up in a 5" diameter tube that is 50" long. The sum parts fit nicely in the corner of the spare bedroom.
