My oldest daughter is a huge Harry Potter fan. She's ALSO a huge American Girl doll fan. We have been on the hunt for a doll we could turn into Hermione for quite a while, and just saw this sweet doll. She is Mila by Our Generation. She had the right face shape and the right color hair. Based on this video, I thought we could straighten her hair *just enough* to make it look like Hermione's fluffy locks.
I used acrylic paints to add her features. I mixed brown paint with a bit of black to get Hermione's signature dark eyebrow color. The above picture, one eyebrow has been painted. I extended her brows in towards the middle a bit and past her eye a bit as well. They aren't perfect but they look pretty good.
I used a skin tone color with a little bit of brown for her freckles. I did a full layer of freckles with that color then added a tiny bit more brown to it to make a slightly darker shade. I also added a layer of paint to her lips in a more natural tone. It helps to add a bit of water to acrylic paint for things like lips so the paint will go on more smoothly and not leave paint lines.
This is a close up comparison of her face painting before and after. It's amazing to me what a big difference a small amount of paint makes!
And finally, the side by side of the factory doll versus our "fixed up" Hermione. My daughter is so happy with her! <3
