Bottom of impact screen - ball return

[larryawade]

Just completed my golf simulator build-out. Got my impact screen from Preston at Par2Pro. Grommets on the top and velcro on the sides. The bottom is just loose and I have an extra 6 inches. I have turf on the floor in front of the screen. Any ideas on some way to fasten the bottom of the screen or weight the bottom so that it creates a ball return?

I'm thinking of having a gentle slope up in my flooring near the screen, hopefully to enable balls that would normally gather there to roll back towards the player.
