Let's get started.
Step 1: Materials
Hairbrush (optional, to take out knots)
Hair (doll or human)
Elastic-I don't have:(:(:(
Step 2: And Now...The Braids
Braid the hair one stitch, so the next strand you have to cross over is on the right.
Add hair to the right strand and cross it over.
Continue braiding the hair, adding hair to the right strand until you reach the ear.
Braid regularly until you have no more hair left to braid and secure it with an elastic.
Voila! You're done!
