I have a pad of post-its infront of me and i wonderd what i coudl do with them and wanted to see what other thigns can be done with them, or what you can make out of one or a couple of them!
Take one post it note. Fold it corner to corner so that it makes a sort of X shape
Then fold the sides in to make a triangle
Fold corners of the triangle up on all sides to the top of the triangle
And you end up with something like this
Now fold the corners into the middle
Do it on all sides
And fold the little points into the pocket like thing
Do this on all sides
Now all you have to do is find the little hole on the top and blow! Tada! A square-ish ball. They can hold water by the way making them perfect for a little water ball fight!
Enjoy and post your ideas!:)
