4mm crochet hook needed for border
66cm at deepest point
164cm at widest point

800m of yarn in total is required for Westcott if you’re knitting with a single strand of laceweight yarn.

If you’re planning to run two laceweight yarns together, or hold them double, as I have done in the photographed sample, you will need 800m of each yarn.

Update: The Westcott shawl is now available to buy as a single pattern from my online shop!
