This hat is knit in a worsted weight yarn. I used Briggs &Little Heritage yarn.  Gauge - 18sts. and 26 rows = 10cm in stocking stitch on 4.5mm DPNs. You can use another Worsted weight yarn as long as you get the gauge. You will need approx. 55 - 65gm/of the Main Colour and 20 -25gm of the Contrast Colour
It is a fairly quick knit hat in 3 size options. Small -(16”-18”), Medium (18”-20”) and Large (20”-22”)
