Taken from It Girl Crochet: "The pineapple motif ingeniously decorates the back of these lacy stockings to create the shaping needed for the calf. Rows of slip stitch
worked through the back loops alternate with rows of double crochet to allow for an elastic, comfortable fit. The heel and toe are worked last, making it easy to replace these areas after they wear out."
This pattern is from It Girl Crochet, pg 105 - Vivant Stockings.
Size C crochet hook (or size needed to obtain gauge), stitch markers, and a tapestry needle are required but not included.
Finished Measurements: 6.75 (7.5, 8.25)" after blocking.
