I have a foam rubber pad with raised edges that does help prevent most ‘rolling’ incidents. However, stuff still goes on the floor - especially the tiny HO scale springs that ‘ping’ quite impressively. For anything with some steel content that gets picked up with a magnet, I have an empty lighter-fuel can covered with various traction magnets removed from 1/32 and HO cars. For brass springs, I have a torch and my hands and knees...
