First step: take out the braids in Addy's hair.
Second step: Dutch braid it. A Dutch braid is a normal braid, except instead of braiding the strands over top of each other, you braid them underneath each other. You also add in strands like a French braid. If that made no sense, here's a Youtube tutorial (if the lovely people who did this tutorial ever see this post: thank you SO much for teaching me how to Dutch braid!):
Third step: Stand back and admire your work.
For this particular hairdo, I did something called a "Dutch flower braid." Again, apply to Youtube for further instructions.
I hope you enjoyed!
Live long and prosper.
