The Charms series patterns are among my favorites that use Warp Displacement. When I was exploring warp displacement last year I spent a lot of time figuring out exactly how to get this sucked-in X look and how best to complement the shape. For warp displacement patterns, these are quite easy to do.
I don’t have a great sample photo of this one. I use the 2″ x 4″ and 2″ x 6″ looms sometimes to test out pattern motifs. The sample photo shows an idea I rejected (repeating R2 on R3). It also shows the pattern in a single color. As long as I was in the neighborhood, I went ahead and drew up a diagram.
