Hey all,
I got this idea after reading Jim Policastro's article on making cloth masks and attaching rock faces to them. This is very similar.
I used some felt and cut it to an irregular shape, spray painted it brown and then added various Woodland Scenics ground foams and bushes to it. You could make these to whatever size you needed and then just hot glue or attach with a spray adhesive to your table top. The mats are quite flexible and you can add them to rolling hills or irregular terrain.
