craftgrrl | Photo Emulsion Silk Screening Paper?

This was probably over a couple years ago now, but I swear I saw it here. I had a link to an online store that sold sheets of photo emulsion like paper. They were kind of green-ish. It was not selling the emulsion liquid, they were actual "refill sheets" for something. You could hold it up to a printed design, submit it to light and it would create a silk screening stencil for you. I had the link in my favorites, but my computer died and Im dying to try these now.

If anyone remembers this, please help me out.

Thanks!
