I have a knack for casting on the exact number of stitches to make hand-dyed yarn pool (hey, everyone needs a superpower, right?), so I’m always on the lookout for ways to break up the color repeats. The tuck stitch caught my eye, but in the round, all of the rows would purled, and I’m not willing to purl an entire pair of socks. And then it hit me: make the socks inside out, so they’re mostly knit, then turn them right side at the end. I peeked inside some handmade socks: a toe-up, figure-eight cast-on looked great from the inside, and so did an after-thought heel.
