You need a square piece of paper. It can have a pattern on it or not. Hey, you can even use Stickie notes!

You need to fold your paper in half diagonally.

Then you need to take the corners and flod it so it's up against the middle crease.

Flip the paper over and fold the corners into the crease again.

Take the thinner part of the paper and fold it back.

Take the way-thinner part of the piece you just folded and fold that to make a beak. Now you are done. These make great massege senders or just little things to make when you have nothing else to do at school. These things can get pretty darned small. I can make one about a centimeter big.
