Speaker cloth has arrived for screen wall. I plan on making large frames, wrapping them, and filling top, bottom, then sides of screen. I have to add blocking on the walls and sides of the screen goal posts to attach the frames to.

How is it best accomplished to attach the removable frames? Velcro? I saw in the newest htotm at AVS the guy used speaker grille snap fittings. Seems great, but not sure if it is adding anything over Velcro....
