This sock pattern is for double knitting for times when only thicker socks will do. I wear mine with my walking boots and wellies. DK socks also make great slipper socks as they’re toasty and warm. The self patterning Knitcol yarn makes knitting these socks as much fun as wearing them. The socks are knitted on double-pointed needles from the cuff down and will fit from shoe size 4-12.
