The heel is the most complex part to understand in the anatomy of a knitted sock. It's a good idea to explore different types of knitted heels to find what you like for your hand-knit socks. Short-row heels are surprisingly more straightforward to execute and look very tidy. Their construction is symmetrical and works well for cuff-down and toe-up socks. In this class, you'll learn to knit the short-row heel using the shadow-wrap short-row technique.

Technique Requirements: knit/purl, cast on/bind off, increase/decrease, working in the round, have knit a few accessories, knowledge and experience with sock construction, short rows

I suggest that you knit a small sock cuff as detailed below and bring it to the class as a WIP, in order to better understand the heel construction, but this is optional. I suggest using worsted-weight yarn leftovers for the sample for class, but note that you may not be able to continue and finish it into an actual sock.

Cast on 48 sts using your preferred cast-on method and join to work in the round using your preferred method for small-circumference knitting.
Work 12 rounds in k1, p1 or k2, p2 ribbing.
Work 1 round in stockinette.
Keep the knitting on the needles.

Worsted-weight yarn in a light color. 3.75 mm / US size 5 circular needles, minimum length 32"/ 80 cm for working magic loop OR set of five 3.75mm / US 5 double-pointed needles.
