My hair is really long (really long!! My sister called it "Pentacostal hair" but actually it's "I don't want to bother to cut my hair" hair) so I really have a lot to pin down because my braids are too long to just go over my head once. But I had a go at the Heidi braids anyway. This text/pictures tutorial and this video tutorial were both cute and helpful.
It wasn't until after I had finished that I remembered that I used to do this hairstyle on my Kirsten doll all the time...!!
