I use CC2 Character Artist as well. I print the counters out (quick note, I make the counters round, not square) on regular 20lb. paper. Then I take some self-adhesive backed magnetic paper (I use business card magnets, you can get these in any office supply store) and attach the printed counters to it, then cut them out. Now the counters have a magnet on the back. To give them the extra weight and heft, I bought a bunch of 1" fender washers from Home Depot, in a box of 100. The magnets stick quite well to the washers and I can use 100 washers on any of the counters.
