i bought something like this a few years ago -- $8 for one sheet pan size liner and i made some tea rings where you cut the dough and twist it open to make a pretty design and i cut the $8 pan liner.... three times  omg

so i think this qvc stuff is pretty cool hopefully difficult to slice but i'm sure i could manage --

I looked at it and stopped dead in my tracks when I read:

"Includes one roll of silicone-reinforced fiberglass mat"

I was told to never cut silpat mats because of the fiberglass in them that would be released due to cutting.  I'd feel the same way about this.  I wouldn't want exposed bits of fiberglass near my food.

AYeah that sounds creepy --

this site also says replace it if gets cut like you said maybenot-- the last sentence in #3 under use & care

idk -- hopefully they (at qvc) got their stuff together and it's a well contained fiberglas? idk

thanks for the heads up
