@knot_bella usually in a normal pattern, you can only do a knot, if all the previous knots are done. You knot from the top towards the bottom. But here you have to break this rule for the arms and legs.
@jagajaga13 for the inside of the arm you have to knot up instead of down and when you get to the body you knot down again. The direction of your knots shoul follow the outline of the gingerbread man.
@jagajaga13 you probably haven't followed the tutorial I've written. You can find it on my profile. You just need to scroll all the way down. It's titled "how to knot an advanced shaped normal pattern".
