September 2026 - NEW update improves the fit of the finished sock and clarity of the pattern writing.

About
The Heartwood Socks are a pair of seamless, toe-up socks. Inspired by their namesake, heartwood - the older, darker wood that provides strength and stability to the cores of larger trees, these socks feature a neat column of heart-shaped cables flowing up the centre of the instep and continuing up the leg.
The pattern includes both written and charted instructions, and is suitable for intermediate knitters.

Construction
Stitches are cast on and increased for the toe. The cable design is then worked across the instep, while the sole is worked in stockinette. Stitches are increased further to form the gusset, after which the heel is turned and the heel flap completed. The cable design is continued up the leg before a short ribbed cuff is worked and stitches are cast off.
