Same design as my Adagio sweater, I had fun to imagine this hat and the mitts too!
If you decide to knit both of them, 100g could be enough, just work the mitts rib part a little shorter .
Yarn: Snaeldan 3 ply, new pure wool, natural shades, light grey:
1 skein 100g/260m: 55g/143m needed.
Circ needle: 3,5-4mm.
1 marker.
1 tapestry needle.

Circ hat= 46 cm & height hat= 20 cm.
Adult size only, rather a small size here, you can adapt a larger one using needle 4&4.5mm. This yarn blooms and softens considerably after washing, you can easely work with needle 4.5mm.
Worked in round from the border to the top, just with 2 or 3 cable stitches.
Chart and written pattern.
Many thanks to Maclader for testing my hat!
