Panorama Fiber Arts double stranded sock blanks are two strands of Hitchhiker Sock yarn (75% Superwash Merino, 25% Nylon) loosely machine knit together and hand painted in Shade Shifting Gradient colorways in order to knit gradient socks that match! Just unravel as you knit. There will be some kinking in the yarn when knitting due to drying in the blank, but blocking your project will relax the yarn and it should not have a significant affect on your gauge. Each blank has two strands of 230 yards each for a total yardage of 460, plenty for a large pair of socks.
