This is a free and gender neutral pattern for a quick bulky hat for adults.
The colowork is short and easy to follow, with no long floats.

You’ll need one skein of each color, but you won’t use 100% of the yarn.

Bonus :
Not tried yet, but I think you can adjust the size for kids

head size 45cm - 1 year old - Cast on 50 stitches
head size 50cm - 4 years old - Cast on 60 stitches

Don’t forget to reduce the rows between end of colorwork and decreases for kids !
