When I used to mix sound regularly, it seemed like every time I turned around, my console tape had disappeared.
It turns out that there are lots of uses besides console labeling on event and show sites.
Here are some other uses you might try
Temporary posting of signs like dressing room assignments
Post daily schedules
Labels on patch cables
Make direction arrows on the floor
Mark edges of the stage and steps
Create “pre” show setup diagrams on the floor
Spike marks on the floor
Temporary name tags
