Tweed stitch belt I've been working on:
Rowan Handknit Cotton, two balls, contrasting colours
3.75mm needles
Cast on 13 sts
Row 1: *K1, slip 1 holding yarn to front (RS) of work, rep from * to last st, K1
Row 2: P2, *slip 1 holding yarn to back (RS) of work, P1, rep from * to last st, K1
Repeat rows. At the same time, change color every four rows. Keep going until belt is as long as you want, or you run out of yarn. Tie nonchalantly.
