The hat is knit seamlessly from the top down in order to make the most of the yarn. I used cicular needles in the magic-loop technique, but feel free to use dpns if you feel more comfortable.
After a flat crown the hat is worked in a simple ribbing, but it would also look smashing with broad stripes (remember to knit all stitches in the first round after a color change!) and/or a pompom…
Size can easily be adapted by going up or down needle sizes, yarn weight or adding/leaving out increase rounds…

Note:
The pattern is free to download, knit and share. You can knit as many hats as you like and keep them or give them away to family, friends, strangers or charity. You are not allowed to sell the pattern or the finished hats unless you want to donate the money received to charity.
Note also:
I am not a native speaker of English. If you find my wording strange or my grammar incorrect, please contact me. Likewise, if you find a mistake in the pattern. I‘ll then try to improve the pattern. Thank you!
