Weaved Chain?

Saw this technique originally on a much bigger chain
One heck of a tedious project.

I did the first side by hand but I had to do the second side with a needle, such a hassle trying to find a needle small enough while still being able to thread it considering carpeting thread is some heavy duty stuff.

Some of the pictures make it show up straight but it twists on it's own, like in the last pictures pretty evenly all over. I have no clue how or why, but I like it better that way anyway.
