I LOVE making Sockhead Hats! Super easy and a great way to use your sock yarn skeins.
Here are some I finished up last month.
I used needle size US 2.5 (3.00mm) for all of them.
The one above uses:
James C Brett Moonlight Sonata DK
This is one skein of
KnitPicks Hawthorne Fingering in Ladd's Addition
Knit Picks Hawthorne Fingering in St. Johns
Knit Picks Stroll Fingering in Mocha Tonal
You can find more information and the free pattern link on my Ravelry project page.
If you are using Patons Sock Yarn, I would suggest using a US 3.0 or 3.25. I found that using the needle recommended in the pattern made for a too tight hat.
Don't have a complete skein for a Sockhead Hat? Gather all your leftover sock yarn and make stripes instead.
