I wouldn't be surprised if this is old news to anyone, but I recently started using toolbox liners as a base for dungeon tiles and Paizo's map packs. They're very handy for keeping individual tiles in place, especially if you play on a kitchen table or other glossy, finished surface.
I haven't had as much slipping with dungeon tiles, since they're a fairly thick stock, but the liners really come into their own with the map pack tiles. Those tiles are fairly thin and slide like butter on a tabletop. With the toolbox liner, they stay nice and snug. I originally tried mounting the on foam board, but the liner makes that pointless work.
Anyway, hopefully someone will find that useful.
