That sounds very interesting and just like something I envisioned! Now to find out who the mystery lady is
I have tried googling for banding, but found nothing. Persistence might be the key here :-) Maybe a hairdresser that specialize in braids might be a way to go.
Thank you all for your very kind replies! And a secial thank you to the lady who reminded about the danger of hurting the dog with too tight braids.
