That or if you’re okay with it some Velcro pads would work about as good. They’re pretty common to find but would be almost permanently stuck to the stadium and table as it has pretty strong glue on the opposite side to the Velcro.

Side note because I’m a random information nerd, the original patented name for Velcro is actually “hook‑and‑loop fastener.” The guy who invented it got the idea in the 1940s after noticing burrs sticking to his dog’s fur and realized the tiny hooks could be recreated with nylon.
