Hi, I do the 'top knot' as you call it, like this.
Using a soft sliker brush, brush the hair completely over to one side, using thinning scissors cut the hair that is longer than the side of the skull. Then brush the hair all over to the opposite side and do the same again. Then brush the hair to the back of the skull, with the thinners trim the hair off the back skull, and trim as far forward as the middle of the head. The top knot should not be flopping forward. A little finger and thumb work to remove some hair from between the eyes and to thin out the front. Do a little, then slicker brush to check how it looks.
Have fun. :)
