Round dehydrator sheets HELP!

[Minnie]

My grandma gave me her old dehydrator a Deco Sonic dehydrator. It has 6 trays but only 4 round teflex sheets. So I can only use 4 at a time for crackers and such. Can someone please tell me where to buy 12” round teflex sheets. Thanks. :D

Minnie :p

pleasanthillgrain.com has round sheets, however, 13.5 is the smallest. Maybe they can be trimmed?
