"After the layers are dry and you are pleased with how they look you'll take the paper towels and roll them up to about the thickness of your thumb, the paper towels should be distorted and "lumpy" in parts.

Leave the ends open and some paper out the ends. When you're done rolling it up squeeze the whole thing in spots so it looks like intestines. I spun them around like a moron and that seemed to help alot."
