There’s less explanation in this post, so if you need photos of the individual procedures, see:

Two-Layer Warping: 2/2 Twill with direction changes after rows 11 and 21

Continuing on from the previous post, R1 is in place and, we’re ready to begin weaving a basic 2/2 twill. Make sure R1 ended by going below the #4 pin at Cr4.

(for Amelia in Korea—thank you for asking!)

• Why do pin loomers use three-layer warping?
• Is it stronger?
• What are the differences between 1-, 2-, and 3-layer warping?
• How do we decide which warping method to use?

For the original post of this pattern see Hearts and Diamonds Overshot. This is a really beautiful pattern in the Pin Loom “overshot” technique. I have this theory that all “overshot” patterns can also be woven using the 2LW method, so I started with the first one I learned: Amber Vigil’s. With her permission, I share my rendition of the pattern here.

If you need instructions on two-layer-warping (2LW), please see instructions in the posts linked below. The first post tells how to warp the loom and weave Row 1. The second post shows the needle path (where to enter and exit the loom) for the first eight rows of a 2LW pattern. For this pattern, follow the diagram below, but follow the needle path instructions; they are universal for all 2LW patterns.

“Multi-Diamonds 4” features diamonds created by going Over and Under on front and back.

Maybe I just don’t do yellow well. By way of excuse, I don’t have a lot of color choices in wool.
(I didn’t add row 32 in this square.)

Not wild about my color choices for this square—I’d prefer a stronger contrast—but you can learn from my mistake.

“Concentric Diamonds” does not begin nor end with a plain weave row—rather daring, I thought, but it works!
