This is the fifth sock of a year-long “Club” of patterns. The entire collection includes 12 sock patterns (plus a few bonus items), representative of different world cities. Click the source page or purchase the club to find out more about the world tour of 2021. The pattern is, therefore, only available as part of the collection until 2022

Skill-level: Intermediate, lace and cable work, as well as optional bead placements.
Yarn: 350-400 yards or 320-360m of sock yarn. The socks pictured are a size M and used approximately 365 yards of Madeline Tosh Twist Light in the color Chamomile.
Beads: Beads are optional, but pretty. I used size 6 glass seed beads. The heavily beaded sock used 72 beads, for an approximately 6.5 inch high sock leg. The less beaded sock used 27 beads in place of the bobbles.
Tools: Cable needle, if required, beading tools (a tiny crochet hook, or, as I prefer, dental floss threaders), scissors, tape measure, and tapestry needle.
Gauge: 8 stitches and 12 rounds per inch or 2.5 cm of stockinette worked in the round.
Sizing: S(M,L,XL) sizes measure approximately 8(9,10,11) inches in circumference
These socks are very elastic. Size down if you need to adjust.

As you can see, there are plenty of options to customize your socks regarding beads, bobbles, both, or neither.
