It's Crafts Time!
Here's what you do: get 30 plastic push-pins like folks use on cork-boards.
Light a candle, and hold the tip of a pin over the flame for 5 seconds (be careful, etc.), then pull the heated metal pin out of the plastic with pliers. With a few strokes across a file, make sure the bottom of the plastic (where the pin used to be) is flat.
Lay out your 30 magnets, keeping a generous distance between them as they will "jump" at each other and mess up your work. Mix up some 5-minute epoxy and put a very small amount on the plastic, then squish it down onto a magnet. Repeat until you have an armada of thumbtack magnets.
Once the glue is set, carefully carry the magnets to your fridge and try them out. The magnets really like to be in a stack with one another, and may destroy the plastic you've just glued on if several are loose together. This won't be an issue once they are stuck to your fridge door.
These magnets are exactly the right size for this application, and the thumbtack handle makes them very easy to place and remove.

These are some strong magnets...
We were constantly having problems keeping all the coupons, invitations, photos, and school projects on the fridge with the cutesy, funny or freebie magnets in our arsenal. We got these to make things stay put.

And they do. These magnets are small, but they are very, very strong. Only trouble is trying to get one separated from the rest! Now all of our refrigerator art is securely fastened to the door.

They're magnets
As the other reviews of these handy little magnets suggest, they are very strong. You have to twist them to get them apart. I used two of these tiny things to attach a decorative wall plaque to the side of a locker.
