I posted on another forum a solution to a problem someone had with the Excalibur and thought I would mention it here.
The problem was when using parchment instead of the Excalibur sheets for drying fruit leathers - the edges would be blown up over the fruit by the fan.
For many years I have been using double-stick tape, the thick kind, with the foam center, to anchor the back edges of bakers parchment in the Excaliburs. it holds the paper securely and it has been easy for me to peel the parchment off the tape and leave it in place for the next piece of parchment.
The regular two-sided tape is not as sticky as the foam center stuff and is less heat resistant.
Anyway, just thought someone might find this of interest.
