I think I would charge $25. Just keep in mind, when she shows it to her friends, you may get more requests, so if you start out with a low price, then everyone will want it for that low price.
I think it's very cute. Great job. I can't help on the price. My niece asked me to make a tote for her like mine and I just gave it to her. I'm not good at pricing.
Very pretty. Good luck trying to sell anything. Seem some people want something for nothing, then they can brag to everyone what a great deal and they paid very little for it.
