ELF HAIR!!
Found via Facebook but then I went and hunted down the name on the watermark and HairByJaneY’s instagram is here and it’s pretty damn awesome. There are a lot of speed-up videos showing how the braids were accomplished, and apparently the same videos exist (at normal speed) as tutorials over on her YouTube channel.
(Also if you just do a google search for “hairbyjaney braids” you get THIS stunning view.)@morgynleri this looks up your alley; are you familiar with her stuff already?
