In this video, we learn how to do a fishtail on your American Girl doll. You will need a doll with longer hair to do this correctly. Brush the hair out, then grab two rubber bands and set aside. Start out by putting the hair into a ponytail with the first rubber band. Then, section the hair off to create a double braid in the hanging hair in the back. This will create a look like a fishtail braid. Continue to do this until you reach the bottom of the hair, then tie it with a rubber band. Enjoy this look on your doll!
