Overview
Two mirrored modular socks are worked with join-as-you go swirly units—no seaming or grafting. The toe and cuff are knit up from the foot and leg units.

The units are something of a puzzle to put together. A diagram that you can cut out and assemble is provided to guide the sock construction. Both written instructions and charts are included.

Units begin from a speedy provisional cast-on onto waste yarn (a built-in lifeline!) combined with knitting up from neighboring units. You won’t lose time getting each unit started, but there will be a few more ends than usual to weave in. Choose textured star units or plain smooth units, placed where guided by the diagram or as you like.

Before you begin
Regular sock construction doesn’t really apply, but it helps to have familiarity with working sock toes and using small needles. You should also be comfortable knitting in the round, increasing, decreasing, and working a provisional cast-on. I like to work these on double-points, but circulars can work too.
