Fabric

[Darrel Meeks]

Does anyone know of a really thin, white fabric that won't disperse a point of light, shining from behind, sideways through its fibers, and thus splashing the light into a much wider pattern? I realize any fiber will conduct some of the light side-ways, but I'm looking for something that will keep the dispersion to a minimum.

Any ideas as to the type of fabric that has this property? Cotton? Nylon? Anything?

I'm not sure exactly what your application is, but it sounds like the
solution may be a double layer of wax paper, ironed together:

Depending on what you're doing and how big you need, projection screen
material can be as low as $16.95 / linear yard:

Or $12 / sq ft if you need smaller pieces:

Thanks, Keith. That gave me some ideas.

I also saw some great material like that at the fabric store when I was looking for tracing paper, the fabric they use to make patterns out of is like that I think ;)
