Golf Simulator Build

I am in the process of wrapping up my shop build. Half is a simulator and the other half is gym/tool area. I have a few minor things to finish like cleaning up the cords for the tv and projector as well as getting more gym mats for the floor (eventually green carpet on top of that). I may hang a black large sheet fabric or felt to catch the flop shots (kind of like a baffle system). Thoughts on that? I am also having an issues with slight movement of mat. I have previously tried carpet tape at my old shop and that didnt work. Any thoughts besides bolting the mat down. I am also using the Mevo +. (Ignore the kids toys those move when I play)
