Measurements

The total circumference of the hat is approximately:

18 inches / 46 cm
19.7 inches / 50 cm
21.3 inches / 54 cm
22.8 inches / 58 cm
24.4 inches / 62 cm
The hat can be stretched about 2 inch / 5 cm to fit a larger head. Knit the size which is closest to your head circumference. (Depending how tight you knit the hat can be stretched even further)

In this sample I used Kelbounrne Woolens Scout and the following colors:
Juniper Heather

Mostly not much is needed of color 2 and 3 therefore it is a perfect leftover project
