One of my favourite second-day hairstyles is the Heidi or Milkmaid braid. It's super simple, yet doesn't look it - I'm always asked how I do it. Which, I think is slightly different to most people, but my hair is very thick and mere grips alone will not hold it!
I've been meaning to do it for ages, but it has taken this long for my hair to finally be in a position for me to do some tutorial business! Yeah man.
Have fun, skipping around with a bunch of goats. Like I do, constantly.
