Yo Ho Knitters,
I'm so kind I finally finish this cute hat with an very interest pattern.
The one you see in the picture is actually no. 2 of it. I did something differently with the top, and ended up knitting with 3 balls of yarn. Still, it was not very satisfying. So I just kept it subtle and started it all over again.
If you are a fast knitter, you can probably finish this hat within a day. Learning from my own experience, I would recommend you to count the number of stitches for every row. I know it's annoying. But trust me. It definitely worth spending the time.
Skills needed for knitting Op. 11 hat are: knit, purl, psso, M1, k2tog, yo, sl 1, knitting in round, cast on, bind off. I will soon do a tutorial for psso for your convenience.
Although this hat knitted with Bobby Blue color, Op. 11 is suitable for both boy and girl.
