First, I tried making the Mohawk following the "METHOD 2: FUZZY CLOTH" described in the instructable made by dan. But I couldn't find that kind of long hair fuzzy cloth.
Then, after some time thinking in what to use instead of that cloth, I "invented" a third method for doing it. I bought a scrubbing brush and I took out the plastic bristles. Then, I made some holes with a drill. Filling the holes with hot glue and putting inside them the plastic bristles was all I had to do to finish my work.
Oh, I forgot. I added some stickers too. I hope you like it.
PD: I'm Spanish, sorry if I committed any grammar mistake.
