That is so cute. They probably just made the pink tutu part & then added the green/white tulle at the top after. You can either sew or glue on the "seeds" or beade.
If you are asking about the tutu itself all it is is making either a basic double knot with the tulle or a slip knot with it around your piece of elastic for the waist.
