How did you turn them into magnets? I have some characters I wanted to turn into magnets, and bought a thin sheet of magnet. I was going to leave them square but this is much better, how did you do it!?
And that is why I put mine on magnets.
Flexible Magnet Sheet With Adhesive, 0.030" Thick, 12" Wide, 24" Length (1 sheet rolled inside tube) https://www.amazon.com/dp/B005HY990G?ref=yo_pop_ma_swf
I just bought one of these and cut it out by hand after sticking them together.
I used this to make my Nats stickers magnetic. This one only works because the nats stickers are solid shapes.

If you are dealing with non solid 1 piece decals, then I would suggest getting a sheet without the adhesive, that way the decal will have a background. Like the gumball number design.

Stick them to this. You can then either simply stick it to a fridge, or frame it on the magnet itself. Either way you have options. An old sticker collector taught me that one.
I made my own in '12. You can buy the magnet stuff on Amazon or probably at craft stores like Michael's.
