Softbox Screen???

[Ralph III]

What is a good soft box screen material? I have a reflector and want to add a screen material in front to help soften and/or further disperse light. I prefer something not too thick as want to avoid having to turn up the power.

Thanks

I've made a few panels and used rip-stop nylon from Joann's Fabrics. It's cheap and works well.
