Free Knitting Pattern

These square Santa hats are so much fun!  Two fun, floppy pompoms are much more festive than one.  I have written the knitting pattern in sizes for everyone in the family so you can knit these up for some awesome holiday family photos and memories (please share!!).   

Affiliate Statement: Hey Readers, the following post contains affiliate links.  I may receive a small commission if you click and purchase from one of these links (which honestly, I’ll probably use to buy more yarn and design more awesome patterns to share with you).  I only recommend products that I already use and love, thank you so much for your support.

Of course, if it’s not always the Holiday season, these hats will also look great in so many other colours and make a great gift too.  Knit them up in your favourite team colours or any combination you like and wear them all winter long.

Check out my Rainbow Square Hat pattern here for a cool striped version.

Beginner Friendly

These are a super easy knit, perfect for someone just starting out in-the-round because there is no increasing or decreasing. If you are a little more advanced you can skip the bind off and use a kitchener stitch for a seamless top.

Not a knitter and still want the hat?  I can knit one up for you. These will be available in my Etsy shop for a limited time. You can find the listing here.
