Three-layer warping technique

About a year ago, I came across a YouTube video by Piglet Evans about a weaving technique using 3-layer warping. (See below for video.)

I made a bunch of potholders using this 3-layer warping technique, but I couldn't figure why these potholders came out better than the ones using the usual weaving technique. I figured it involved some sort of "weaving magic."

But it turns out that this technique of alternating colors and skipping rows creates a consistent weave. The first step of warping the loom (that is, attaching the parallel loops across the loom) and then rotating the loom and working in both directions creates a balanced warp.

That sounds complicated, but the technique is easy. To show you what's involved, I've made a potholder using this technique.

Step one:

Starting from the top, attach loops on every other peg:

Step two:

Rotate the loom and attach the next color (here, robin's egg blue). Again, starting from the top, attach a loop on every other peg.:

Step three:

Rotate again and attach third color (here, dark blue) on the empty pegs between first color (yellow) loops:

Step four: Rotate again and weave in the fourth color (white loops) on the empty pegs. See video below for how to weave in the loops, starting in the middle and then weaving in the loops first on the right, then on the left.

Finished potholder:

The video below doesn't have sound, but she goes very slowly and it's easy to follow along with each step.
