Harlequin Gambit is a reversible triangle scarf with Harlequin diamonds on one face and a Checkmate grid on the other. Worked side to side in two-pattern double knitting, it brings two independent geometric designs together in one fabric, finished with 3-stitch i-cord edges.

One size: approximately 112 cm across the top edge and 37 cm at the centre, excluding the added i-cord. These are gauge-based estimates; finished measurements vary with yarn, tension and blocking.
