You can use as many colours as you like, but you’ll need at least two yarns with good colour contrast so that the pattern will show nicely.

Work the hat in thicker yarn and larger needles for an adult size. I used 3.75mm and 4,25mm for an adult size small-medium.

I am not a professional designer and only I have knitted this pattern prior to publishing it. Please let me know if I have made any mistakes!
