I don’t know whether I ever told you this, but I learned braiding at a pretty young age. I think my mum taught my brother (!) and me how to do it, as a way to occupy us or something, but I learned it, and for a while it was the coolest thing to do.
I also know a few people who are my age or older who never learned how to braid, For this reason I decided to introduce you to braiding, tell you what dto do and then explain to you how I learned how to braid.
When you do basic braiding, you take three strands. Let’s call them 1, 2 and 3.
At the beginning we have 1/2/3.
You then take 1 and put it over 2. Now we have 2/1/3.
You do the same on the right. Put 3 over 1 so we have 2/3/1.We repeat this on the left, so 2 over 3: 3/2/1
Afterwards we do this on the right by putting 1 over 2: 3/1/2
Next thing we repeat it on the left, so 3 over 1 is 1/3/2.
Now we put 2 over 3 so: 1/2/3
Then we start over.
Tl;dr: You put the left strand in the middle, then you put the right strand in the middle, then you put the left strand in the middle and so on.
I learned braiding by knotting three pieces of string to a handle of some sorts, and then started braiding it using only one piece of string as a strand.
Eventually you can move to your hair, where you have to pay attention to not mixing up the strands (like taking hair from strand 1 and adding it to strand 2).
For french braiding, you go ahead and add a bit of hair to your outer strand before you put it in the middle so basically:
Take hair to left strand, put the entire thing in the middle, take hair to right strand and put the entire strand in the middle, take hair to left strand and put the entire thing in the middle and there you go on and on.
Dutch braiding is basically the same technique, the only difference is that you don’t take the outer strands and take them over the middle strand, you now let the middle strand be the upper one.
