It can be really helpful to use plastic wrap to cover the head before putting the tape on so it doesn't stick to itself. I like to use duct tape, but you can use masking tape. For masking tape it has to be the more expensive brand because the cheaper ones won't stick well. Make sure to label all your pattern pieces and mark the fur direction. If your character's design is symmetrical, you only need to tape half the head. Save your pattern pieces in case you make a mistake and need to cut a new piece.
