Impact screen for foam balls

[Ivo]

I bought a floorstand beamer screen. ( example: http://g02.a.alicdn.com/kf/HTB1_0e8L...ont-font-b.jpg)

I hoped that I could use it to hit foam balls at. Unfortunately the balls bounce back very hard. Does anyone know a solution for this?
Or can you advice me in building my own impact screen? What material should I use? Should it be strained?

I can't speak to how to make the floor stand work but can tell you all I use is a cloth painters tarp I got from Harbor Freight. I bought some grommets and grommet tool and put them across the top and use shower curtain rings to attach to a 1/2" black iron pipe I installed in garage. At some point I plan on building a frame for it but not high on priority list right now. I just have to adjust it every now and then when playing a round. It projects a decent picture and handles the foam balls with no problems. It was also very cheap. I think around $17 and the grommets about $5.
