In the chart, column 19 should be whited out from rows 59 through 86 (knit this stitch in those rows), not greyed out after row 58.

Great pattern, easy to follow. I made the XL size and used nearly a full skein of yarn - there was 1.8 g remaining. Thank you to Otismurph for this yarn and Star Athena for this pattern, which I won through the Indie Design Gift-A-Long.

I used Jeny’s Stretchy Slipknot Cast-On, which made the ribbing excellently stretchy. The link to this cast-on is here, and I used a youtube tutorial by a different knitter, linked here.

I would be interested in adapting this pattern to a toe-up sock so that I could use a full skein of yarn.
