Skill-level: Intermediate, some cabling (one two-cable-needle stitch), chart reading, & pattern interpretation (these are sort of choose-your-own-adventure socks)
Materials: Approximately 350-400 yards (320-375m) of sock yarn. The socks pictured are a size medium and used approximately 380 yards of Neighborhood Fiber Co’s Studio Sock in the color Rock Creek Park.
Needles: US 1 (2.25mm) sock needles (pattern is written for either DPN or Magic Loop)
Tools: 2 cable needles, measuring tape, scissors, tapestry needle
Gauge: 8 stitches and 12 rounds per inch or 2.5cm in Stockinette stitch
Sizing: Small (Medium, Large, Extra-large) socks measure approximately 8(9,10,11) inches or 20.3(22.9,25.4,27.9) cm in circumference. The leg height, ankle depth, and foot length are all adjustable to size and preference.
Note on sizing: this sock is primarily ribbing, and thus very elastic. It is very forgiving in terms of fit, but if in doubt on sizing, go down a size.
