I've got these little (3 cm corner to corner, 2.4 cm side to side, about 2–3 mm thick) hexagonal wooden tiles I'm planning to use in my D&D campaigns. I plan to paint them on both sides, with one side nature-ish (grass, rivers, etc.) and one side indoors (cavern, wooden floorboard, carpet, etc.).
However, the biggest issue I'm facing is their movement. Unless the miniatures are picked up very carefully, the tiles will start to move, which can pretty quickly mess up the whole board. Of course, once painted, the drag will increase and they will be harder to move, but I figured I could still post the problem here and see if I can get a solution to this problem.

Solutions I've thought of
These are some possible fixes I've come up with. However, none of them have been tried in practice yet! If you have experience with any of these, and think it's the solution to my problem, please feel free to answer!
Get a large silicone plate / tray or piece of heavy cloth to place them on.
This would hopefully decrease possible movement enough. However, it can be somewhat impractical to store.
Get a large "sticky" surface to place them on.
Would work fine, except the paint would wear off fairly quickly, which means I can't double paint the tiles. Increases cost a lot
Metal sheet with magnets on the bottom of the tiles.
Same as above, increases cost a lot and tiles can't be double faced.
Get a plate with enough size to hold exactly X tiles, so they can all be clicked in place restricting movement
Best solution IMO, but also takes up a lot of space and forces map to be of size X.
Does anyone have experience with restricting movement of custom terrain? If so, what did you do to solve it, and does it work as planned?
