This screen is fiberglass--it's the same screen that you can get at your local hardware store.  

When you go to the hardware store, you'll find there are several choices of screens.  Any will work, as long as it's NOT metal.  Fiberglass, nylon or other materials work just fine.  

You can choose between "regular" fiberglass screen (what you'll get here) or "invisible" or "pet".  Each can give you a slightly different result, such as a subtle "linen texture" on the surface of your finished silk fusion.
