find some newspaper

Cut it into a square. It doesn't have to be super precise or anything, but it does help. If your just starting I would try this with a bigger square first.

Fold your paper twice, both hamburger and hot dog style. (I colored the lines in with a green marker.)

Basically, you just fold the corners into the middle. After you're done folding, just turn it over.

Now you should be looking at the back......

....Now fold the back corners in.
(you can do the flip over and fold thing as many times as you want to, it gives you more petals.)

Now you're going to fold the corners again. But you only make a super tiny fold. Sorry you can't see it very well :/

This is a picture of the back, your going to take these flaps and fold them up to the other side.

When you fold the flaps over from the back it helps if you put a finger over the tiny fold you made earlier.

It should hopefully come out looking like this, but it's a bit hard at first. Just do this with the rest of the flaps from the back.

And there you have it folks!
