i made this in class after a test... it is a little thing that will jump across a flat surface with almost no effort (if you think your cool, you can follow the pics, but if you aren't sure, just follow the steps)
Step 1Your Paper
iImage Information

your paper should be small it doesn't have to be square but it helps if it is. As stated in the below comments, a notecard, cardstock, or even tickets (like for getting into events, like the "admit one" things) that is the thing i really like about these little things, you can make them anywhere, out of almost anything (as opposed to the frogs [no offense if you like the frog things])
