Sordid Affair Socks is a charted slip-stitch mosaic sock pattern consisting of a mirrored 16-stitch repeat. The pattern is written for toe-up socks using magic loop with an afterthought heel. Other heel styles can be substituted to create a sock with a flattering fit. This pattern is written for the sock knitter who is familiar with sock construction but has not attempted to introduce colorwork to a sock pattern.
