Knit your own Sock-Not Leggings using these clearly-written instructions by knitwear designer Jackie E-S of HeartStrings FiberArts.
Sock-Not Leggings are a unique concept in socks -- dressy stirrup-type legwear without the heels and toes of conventional socks. Sock-Not Leggings are nice as a pretty cover-up on legs without the bulk of a complete sock.
The tailored twist-stitch lace patterns enhance the leg portion, and becomingly conform to the shape at calf. Twist-stitch ribbing on the foot portion hugs ankle and arch. Altogether, a practical fashion alternative for warmth and wearability.
