I have a large mat. Can I cut it into two pieces to use on my cookie pans?
I was sure you can not cut it, so googled it and found the reason.

Do not use scrapers or brushes to clean SILPAT.
Never cut the SILPAT or cut ON the SILPAT.
Do not fold the SILPAT.
Do not grease the SILPAT. It doesnt need it.
Never use a cut or ripped SILPAT as the fiberglass mesh material could migrate into the food.
Avoid using automatic dishwashers, as they may harm the SILPAT.
Do not use SILPAT with a broiler, a grill, or place directly on the bottom of an oven.
