Hey Miriam,
It is sold by Farmtek, the link is in the first post of this thread. Here are the prices. If you get thicker than the 1/16th it gets rather expensive, and if you are building a 5 footer, only the 1/16th comes that wide and in a 10 foot length. They ship UPS, and my last order of 4 sheets was around $85.00 and over $30.00 to ship.

gman,
It is not that translucent. The lady I talked to at Farmtek had told me light would not shine through it, so I was expecting it to be non-translucent. You can see from the pics that's not the case. But it is not translucent enough to put lights behind.
