Cable cast on 77stitches on a 5.5mm circular needle or double points. Knit. Change colour. Knit more. Then when it looks about right, (K9, K2tog) to end. K next round. (K8, K2tog) to end, and so on, until you get down to 7 stitches then gather them up and weave in the ends.
The cardigan I bought at the Leura markets.
