Wine cable knitted hat - Step-by-step tutorial here. size US 4 circulars. could use larger needles tho. she said multiples of so could use less stitches anyways, some say its quite large. or could make a child size.
This scarf is knitted in a heavy laceweight / light fingering yarn, but would look equally good (if not better) knitted in a lace weight yarn. The lace is worked on odd rows, with even rows being ‘rest’ rows, worked just purl.
