Can someone rule-splain this

I assume you clip the blue “end” to the top of your head temporarily at step 4?

You don't need to clip it. It just rests there. The blue loop gets placed through the pink loop and the rest of the hair attached to the blue loop rests on top in Step 7. The "rubber band" is also removed as it's no longer needed. (Will explain this at the end)

what goes through the pink loop at the end? Just the aforentioned “end”?

The 'blue' loop of hair that's tied up.

how many hair ties are you left with in your hair at the end? 0? 1? 2?

The instructions leave both in. I say it depends on your own hair density. You can leave the blue one in if you want/need more volume, as it's another "bump" so it doesn't rest flat. It's possible to do it both with and without the one on the blue section of hair.

Of course. This 'guide' completely avoids the topic of hair density, and not everyone is going to be able to use this style if the hair is naturally thin. It also helps if your hair doesn't naturally rest straight. A bit of waviness is definitely the way to go.

Sorry for editing so much. I'm realizing that there are a couple ways you could do this, and I'm attempting to be as clear as possible. My most recent realization is that the end of the blue loop probably is the last part to get folded over after everything else is done.
