Thanks to pinterest, I saw this idea here for magnets made out of old computer keyboards! My dad works in the computer industry, so thankfully he had plenty of old keyboards he was willing to sacrifice for my crafting endeavors!
Here is a quick rundown. Pull keys off- pliers or your fingers!
Then if they look like mine, you have to break the inside, and pull it off, so it wont stick out too far
then hot glue magnets inside!
