I may eventually say the same thing for all the two-layer, two-color warping configurations; I don’t use them often, but it’s useful to know how to do them when you want them. This one is probably my least favorite warping configuration which is interesting to me because it’s the same configuration generally used on a rigid heddle loom—warp one color, weft another. If you want to practice a weaving pattern you have in mind for a rigid heddle project, this pin loom warping configuration should be useful for that—especially if every odd row in your RH project is plain weave.
In all my years weaving I think I’ve only used this warping configuration once before tonight, but I could be wrong. In the green-and-white finished sample square you can see the interesting effect, along the top and bottom, of changing colors L2-only, so I’d say this configuration is worth exploring.

WARPING THE LOOM FOR COLOR CHANGE AFTER L1

Lay in the warp for L1 only. Note yarn twist at Cr1 (illustrated in the previous post). Keep reverse slip knot (RSK) near Cr3 loose. Tie off L1 outside 2-4 edge pins at Cr4.
