Green foam moss, hairpins, hairspray/foam, a hair elastic and a hairbrush.
Decoration: Butterflies from a flower decoration or whatever you can find.
Shape the green foam moss with a rounding in the top. You do so by marking where to cut and then cut with a knife.
Part your hair in the back of your head, and tie the hair in the front of the parting in a nut.
Place the foam moss on the parting, and take the hair from the back and cover the back side of the foam moss.
Now take the hair from the front and the back and make a small ponytail on the top of the foam.
Put hairpins and hairfoam in the hair so everything is held in place, and then hide the ponytail.
Now you have a spectacular hairstyle, but if you want to you can decorate it. Ex. with butterflies from a flower decoration or a hat made of sponges.
