Here are the pictures.
The first picture is my first attempt, Lola did not want her picture taken lol. The second is today, I love the way it looks with a bow in front. Both were done with a big (size M) crochet hook.
Her topknot has been flopping in her face (I've cut it, taken different amounts of hair, tried different angles, etc), so this is a good solution.
I ordered this pony flip tool, the small end of the smaller one should work well.
