I’m not sure about where you are in the world, but here in Montana we’ve been getting a lot of snow the past few weeks. So of course, my kids have been raiding our hat bin to keep warm as they play outside in the snow. One of the favorites they tend to gravitate towards is Mason Beanie.

It’s got a simple bobble pattern to add a fun texture. Mason Beanie is also made in the ever popular Cascade 220, so it’s an easy yarn to find or substitute. I then added the folded over brim for added warmth for your ears.

Mason Beanie was my personal favorite of the patterns in my 2021 year of hats. I created 1 hat for every month. It was such a huge challenge. I designed 12 hats in 2 months. I probably wont do that ever again because it was so hard to have variety but stay in my style lane, but I am very glad I did it. I learned so much and ended up with this awesome hat to share with you.
