First is my first of many ideas trapped in my Trello waiting for daylight:
"Hair Braiding Class for Parents"
I am a father. I have a 3-year-old daughter. I cut her hair only once when she's 2 months old. Now that her hair is considerably long, any parents would want to tie their child's hair stylishly. Sadly, I only know how to do a ponytail. My wife as well.
Watching tutorials on YouTube is an option, but not a good one. My daughter is very active and she would not have the patience to wait for me tieing her hair while watching the hair braiding tutorial at the same time. A hair braiding class should have mannequins (or perhaps only the head) with different hair lengths for hair braiding simulation. Simulation is a very good way to learn things. Even pilots do simulation training. Why wouldn't hair braiding too?
A class will also encourage parents to learn and practice. I can watch the tutorials on YouTube all day, but I will still only do a ponytail. A teacher showing the step by step in front of you is great, moreover, you can see it from any angle. You can also explore those hair braiding skills that require more expertise as well.
Not bad huh?
