I haven't had much luck with the magnetic paper. I have some older graphics that I made on magnet paper a long time ago and still use, but I reinforce them with the small round super-strong magnets in the corners. When I create new graphics, I laminate them and use magnetic strips on the back (comes in 8 1/2 x 11 sheets and you cut it to size). I have also used the roles of magnetic tape in the past also but found that peels up too easily due to being stored in a roll. So the flat magnet sheets have worked out the best for me.
