Okay, so you've got a fairly standard mohawk, but you wake up one morning and feel like doing something a bit different with it just for the day. How can you make it look a bit different, a bit interesting, without cutting it or losing your main mohawk shape?
Today, I have La Roux hair (but purple). I made it by pulling the back and the crown up and forward into like a ridge or speedbump up the back of my head. The front I fanned out and forward in a diagonal crest rooted at the forward end of the crown. The fan ends perfectly horizontally at a point roughly ten inches in front of my forehead.
Tools: got-2-b-glued and a hairdryer.
