My fox experience led to playing around with color change, seeing what happens when you change color in some rotation. I had to play again to reconstruct what happened in the photo below, but it was fun to do.
This is all in single crochet, of course, the center of my crochet universe. The picture above is of a piece rather unhelpfully made partly in variegated yarn; I tried to give more visual information when I recreated it. Working from the bottom up in the picture below, starting and ending with two rounds of single-color stitching and with a round of single-color in between each of the following, is a single round of alternating loops of each of two colors, another single round but with the position of the colors swapped, paired rounds of each of those situations, and finally a single and then three rounds of three colors in rotation, one loop in each at a time. In the single round of three-color work I pulled loops in the order blue, yellow, red. In the second I pulled blue, red, yellow; there are three rounds instead of two because when I started round 2 I realized that I was pulling a loop of red through a red stitch-top, and likewise for the other colors, so at the end of that round I inserted an additional loop of blue and made a round where the colors did not match.
This work is somewhat less elastic than crochet usually is, but not terribly so (you do have to make sure not to pull your yarn tight, as with any color work). If you like the look of duplicate stitch embroidery on knitting, this is probably the easiest way to get it in crochet – it’s not an exact match, but I’m not sure such a thing is possible, and you don’t have to do any embroidering!
