Hat chops take some preparation and practice, then they are quickly done. This is how I do them.

Important: If your hair texture is mapped on the hat area, you do not need to make hat chops because the hair texture will go over the hat (srsly, try to avoid that. many accessoires like bags are mapped on the hat area too.)
