My method of making those semi-popular keyboard fridge magnets.

Step 1: Step 1

Tear up a broken keyboard.

If you don't own a broken keyboard buy one at a thrift store;
there's a 73% chance it's defective somehow.

Step 2: Step 2

Cut "business card sticky magnets"to fit each key.

I got mine at FedEx/Kinko's. It's a good idea to add
superglue to make sure the keys stick permanently.

Step 3: Step 3

Divide the keys evenly & color with chalk.

Experiment with different mediums to see what
you prefer. I like chalk because it allows for the
original symbols to be visible under the color.
