Rows 3 and 4 of the Heel-st patt on page 85 should read:
Work Rows 3 and 4 with dark and light.
Row 3: K3 with dark, *P1 with light, P1 with dark, rep from * to last 3
sts, P3 with dark.
Row 4: P3 with dark, *K1 with dark, sl 1, rep from *, weaving in light
color across to last 3 sts, K3 with dark. /
I haven't checked these yet, but I will when I do sock #2! I'll let you all know how it goes.
