Caladan was the home planet of House Atreides before they were relocated to Arakis. This planet was described as mostly ocean, but the land was scattered with mountains and rivers. Trade on the planet was centered around the fishing industry. These socks are knit top down with an afterthought heel. There are two charts included for a light main color or dark main color. Flip the colors on the second sock for a pair of fraternal twins. The chart is only worked on the leg and the foot is finished with fun stripes to showcase ombre yarns. Pattern is written for two yarn weights, dk or fingering. If you know you work stranded colorwork tightly, go up a needle size on the charted cuff portion.
