The yarn for these socks is Lorna’s Laces Shepard Sock. It came as five mini skeins. To change from color A to color B, I knit with color A, then did 1 row B, 2 rows A, 1 row B, 2 rows A, 1 B, 1 A, 1 B, 1 A, 2 B, 1 A, 2 B, 1 A, and then continued knitting with color B. I think, in hindsight, I’d do at least one more 1 A, 1 B alternation in the middle, particularly with the more different colors. Still, I’m pleased with how the colors blended together, and I think they look okay. I used the same style of decreases after the heel that I’ve been using for the mosaic socks, so that I could see what it looked like without the mosaic hiding it, though it turns out the speckled yarn does a pretty good job of hiding the decreases too! I used just over half the stitches for the heel flap, as I wanted the heel to show up more visually, since it’s in the different color. In past I’ve sometimes been unhappy with how small the toe and heel look when they are the only thing in a contrasting color, but I think these socks are fairly well balanced.
