Rear Screen Projection Material

I've tried dozens of materials, and to my eye/tastes, nothing works better
than drafting velum (brand name escapes me, but I can find it later). I know
it comes rolled up in a orange plastic cover, with widths from about 2 to 5
feet.

I prefer this material because it is low on grain, and high on light
transmission. I've put it behind Kodalith (film negatives) titles and rear
projected images onto it, which I then filmed from the front.

Bouncing a rear-projected image off a 45 degree-angled mirror keeps the
image orientation as if it were front projected, as well as diffuses the
projector bulb hotspot.
