I've seen lots of stuff about teflex sheets for Excalibur dehydrators, but we have a L'Equip dehydrator and I can't find anything similar for that type. The L'equip ones have a hole in the middle for the air, so if we just got a few teflex sheets, we'd have to cut a hole in them. Are there any teflex sheets for that kind of dehydrator? What do you guys use?
