To make a part, use the front two teeth of a comb to draw a line across the scalp. Divide hair at the top of the comb and separate. If you draw a straight line, the part will be straight. If you draw a curved line, the part will be curved. Draw a zigzag for a zigzag part, though you may find it easier to do small zigzags with the tail end of a rat tail comb. For large zigzags, do a zig, separate the hair, then do a zag and separate. If you try to turn a corner with one stroke, you may get to much hair in the comb to manage.
