I sat down in front of Sarah for about 30 minutes and this is what appeared in my hair. This is a braid with 23 strands. It began as a 3 stranded braid into which she incorporated 2 strands at a time kind of like a doing a french braid. If you're looking for instructions on how to do a multi-strand braid, odd-numbered strand braid, or just braids in general please feel free to contract me.
Sarah is also the lovely lady who created this Katara hairstyle.
