So, in my quest to devise a way to keep stuff in place, consider this:
A large, vinyl, magnetic mat. They sell them. They are mainly used for magnetic signs like you see on vehicles. However, I'm thinking about using one as a play area, and putting something on my bases (magnetic tape, glue a magnet to it, something) to keep things in place.
Of course my opponent won't benefit from this, unless he has the same setup.
Here is the site I was perusing:

All different sizes, colors, thicknesses.
I could get a roll, black, 2' by 10'. Cut it in three 2X3 strips and butt them together.
They also do custom . . . way more expensive though.
Anyone think this might work? Already been tried? Or am I just getting crazy with this . . .
