I have always thought it would be super fun to design custom origami paper! This one is definitely a first effort, doesn't have an opposite side or cutting lines, but I did make a jumping frog out of it and it looks PRETTY SWAG. Shockingly the way I learned to fold frogs is apparently not standard?? http://www.wikihow.com/Make-an-Origami-Jumping-Frog is the closest I found online.
