Crochet Brain Beanie – a FREE Pattern

So you may have heard about a “March for Science” on Washington. This is a nationally organized protest scheduled for April 22, 2017 all around the country, but primarily in Washington, D.C. at the National Mall. Scientists nationwide are planning to make their voices heard on that day, which also happens to be Earth Day, to protest the current administration’s policies on the environment and scientific evidence. Whatever your politics may be, I think it is a wonderful thing that we can peacefully protest and make our passions known in this country without fear of reprisal. What in the world does this have to do with crochet, you might ask? Well, you may remember the recent Women’s March and its universally recognized symbol of the crocheted “Pink Pussy Hat”? Well we cannot leave the scientists out – the symbol being talked about for this march is the crochet Brain Beanie!

My husband, a self-professed geek and lover of logic, linked me this post and said, “I want one!”

First I made this face and said:

And then I thought, well yeah that’s actually pretty cool! I started looking on Ravelry for crochet brain beanie patterns, but I couldn’t find one I was in love with, so I decided to make my own!

I really love how it turned out and I think my husband looks pretty cute in it too!

This pattern is fairly easy, as it is a basic beanie, but with a bunch of tubing stitched to the top!

Row 2: ch 2, DC into each DC around, join to first DC (5)
Row 3 and up: repeat row 2 until you reach desired length. Finish off, leaving a VERY long tail for stitching to the beanie. Stitch the hole closed by gathering each loop of the 5 DC together and pulling tight.
*I did not measure the final length or number of rows for my tubing, because it is based on your preference for how you want to wrap the tubes on the side of the hat and how tight you want to make it. My tubes were more than twice as long as the length of my arm, and I still ended up needing to make another smaller piece to fill in a hole that was bothering me!
Attaching the tubing:
I would recommend you loosely run a line of dark contrasting yarn down the very center of your beanie to divide your “brain” in half and use as a stitching guide. It can be very easy to get off center when you are dealing with very long pieces! You’ll notice that mine is a bit off center from not following my own advice!

Pick a spot near the back of your hat, just above the brim and attach the yarn tubing. I ran the stitching INSIDE the tubing and poked it out where I wanted to attach it to make a small stitch, then ran it back inside the tubing to hide it. Randomly loop back and forth in rows and loops like the sulci on a human brain. One long tube should be attached only on the right side, and the other long tube should be attached only on the left side. The human brain is divided into halves, and they do not visibly cross, that is why there are two separate tubes! Once the entire tube is stitched down, weave the end into the inside of the beanie a few times to ensure it stays in place.

      My Mum is a Lab Tech at a high school, I think this would be an awesome gift for her, especially when her prep rooms get so cold through the winter! I might need to make one for their Science Co-ordinator too! lol

    First of all I love your sense of humor it tickled me. I wonder if my eyes roll in my head when I tell my son-in-law that knitting is different from crochet LOL I’m looking forward to doing your pattern. I just completed one pattern that work together fairly quickly but I would have preferred they have to have a rib on the edge as yours does. Another thing the pattern that I found the person suggested gluing it down and I just don’t think glue would hold on a knit cap that might get tossed in the washing machine and dryer. I’m looking forward to making it but I am dreading stitching down the brain tubing. I think it might be probably the most time-consuming of the entire project. If you have any other tips for making it go any easier please let me know. Anyway thank you so much for your beautiful mind and your beautiful pattern.

      Thank you for your sweet comments Rita! I hope you’ll share your completed hat with me when you’re done! I agree that glue would not be my preference, but the stitching part wasn’t too bad. I would definitely recommend pinning first though, it’s more challenging to keep straight than I had anticipated!!!
