Nice pattern, even though I’m not very fond of beads in socks - here they are just in place.

Errata in clue 4:
Gusset decrease: round 2, heel stitches should start k15 for size S, not k16. All other rounds should be adjusted, too.
Toe: round 1, Instep stitches - k1, ssk, k until 3 sts remain, k2tog, k1 (the same as for heel stitches)

63 sts (size S)
24 beads/sock

Toho Round beads, size 8/0
