The geometric colourwork design featured on this hat was inspired by the beautiful pattern of lines seen on Auriga butterfly fish.

The hat features a double rib for extra cosy warmth around your ears, and a geometric colourwork pattern over the main body of the hat. Worked bottom up, a provisional cast on is used and the rib is worked flat. The rib is then folded double and knitted in place before working the colourwork body of the hat in the round. The small seam of the rib is stitched when finishing the hat. Suggestions are included in the pattern for adapting the rib style and adjusting the circumference of the hat.

This pattern is suitable for intermediate knitters.

SKILLS REQUIRED: provisional cast on, working flat, working in the round using a circular needle, working a smaller circumference in the round using dpns (or preferred method e.g. magic loop), knit, purl, k2tog, stranded colourwork following a chart, oversewing a small seam.

SIZING
To fit approximate head circumference: 21.5(22.5,23.5)”/54.5(57,59.5)cm
