This terrific stuff is also sometimes called Teflon paper. I've used it for years for baking cookies. Now I use it for PMC. I take the 13" x 17" sheet and cut it into smaller pieces, then work my PMC on top of the Super Parchment. Then if my piece is too delicate or wet to move, I can easily move the piece on the Super Parchment - to get it off of my work surface, or onto my mug warmer to dry.
My students have a dickens of a time finding this stuff - even at stores that are known to have sold it before. So I knew I had to find a source for it to bring it to you.
You can cut through this if you use an X-acto knife or it or press very, very hard with a cookie cutter. Leaves a very faint woven design impression on the back of your clay. Washable and reusable.
Set of two plastic work surfaces. Inexpensive, so you can have extras around. It's nice to be able to move one project aside to dry while you work on another one. Sold per set.
Same as the above, only in a 12" x 12" work surface!
