With gentle waves in a variegated yarn this beanie is the ideal way to add colour to your winter wardrobe. It is knitted flat and seamed, with instructions for seven sizes, from preemie to adult:

Circumference
11.5, 13, 15, 16.5, 18.5, 20, 22”
30, 33, 38, 43, 48, 53, 58cm

Yarn
10, 15, 20, 25, 25, 30, 30g main colour
15, 15, 20, 25, 30, 35, 35g contrast colour

I used Hayfield Bonus DK but any yarn that works to 22 st and 30 rows to 10cm (4”) over stocking stitch should work just as well. If you use a different yarn, please check the yardage carefully.
