This is like the marriage of rising darkness and a classic Breton striped fisherman’s sweater…You start at the bottom with the darkest color, and slowly with fair-isle technique mingle in lighter and lighter colors until you end up at the top with your lightest brightest color.
It’s knit in the round, bottom-up. The sleeves are knit separate and combined with the body at the start of the arm opening. The neckband is picked up and knit. Create your own gradient, and maybe use up your remnant sock yarns…
