Anyone use interlocking foam mats for hole covers?

I used a cheap sleeping pad, $7.99 at walmart, to make hole covers. Easily enough material for at least ten covers.

I used the interlocking foam mats and they work great.  Another tip...Use the foil emergency blankets and cover the hole side.  Spray glue.  Traps the heat even better.  BTW they are not only useful for keeping the hole open, but also keep a beam of light from entering the water column.  Fish have to be able to see that.  Especially in shallow water.

Some of the older posts on this topic may be hard to find so it's not a bad idea to circle back from time to time and stir folk's imagination once more. You'll find references to guys cutting up plywood, hardboard siding, old mud flaps, old floor mats, inner tubes,  L-P records, Frisbees, and various foam sources to duplicate the commercial ones. It seems like if you're just sitting there staring at a hole in the ice at some point your mind is going to try to find something useful to think about like making some hole covers.

That is what I did, had some laying around from when the kids were younger. I got 2 covers out of one square. Made 4 total. Used another mat and cut in half to keep feet off ice.
