Let’s Knit a Brain Hat!
MARCH FOR SCIENCE: Science-loving brainiacs wore my knitted Brain Hats at the March for Science in DC, across cities throughout the US, and even some international events, too!

KNITTING TECHNIQUES for the Brain Hat
• Slip Knot
• Cast On
• Knit an I-Cord
• Spool Knitting I-Cords on a Loom (for non-knitters)
• Embellish Knit Machine (for non-knitters)
• Knit Stitch
• Purl Stitch
• Knit in the Round Circular Needles
• Switching to DPNs
• Worsted Weighted Yarn, in any fiber/colors of your choice
• 1 Circular Knitting Needle (for Hat) – Size 8 US, 16″ long

KNITTED HAT BRAIN BASE
You may either knit up a new hat base, or recycle any existing hat. The more gray matter you add to your hat, the less you’ll be able to see the hat base. So, you can use either the same color hat as your gray matter or different. It’s totally up to you.
To begin, we will use our circular needles and the four size 8 DPNS to knit up an easy 5 by 3 ribbed hat as our base.
1 – Size 8 US Circular Needle, 16” in length
4 – Size 8 Double Pointed Needles
Worsted Weighted Yarn
Cast on 80 Stitches using the Cable Cast On Method.
Join in the Round, being careful not to twist your stitches.
Knit in the 5 x 3 Rib Pattern (K5, P3) until your hat measures 5 ½ inches in height.
Crown Decreases (Switch to DPNs when necessary)
Row 1: * K2Tog, K3, P3 * (repeat between each *)
Row 2: * K2Tog, K2, P3 *
Row 3: * K3, P2Tog, P1 *
Row 4: * K2tog, K1, P2 *
Row 5: * K2, P2Tog *
Row 6: * K1, K2Tog *
Row 7: * K2Tog *
Row 8: * K2Tog *
Draw Yarn through remaining loops with a tapestry needle, cinch, weave in ends.
KNIT GRAY MATTER WITH I-CORDS
This is a great project if you love making I-Cords since we are going to knit up a lot! I mean, a LOT!!! Feel free to get really creative with your yarn weight, color, and even fiber.
Let’s Knit Up Some Brains!
• Cast On 4 or 5 Stitches and Knit an I-Cord in various lengths of your choice
• Bind Off each completed I-Cord once they reach the length you desire.
I-Cord Length: My longest I-Cords are 28 inches in length and my shortest are just three inches long. Any sizes totally works because you will create your own brain pattern onto your Brain Hat.
I-Cord Volume: I knitted up over 17 feet of I-Cords for my brains… that’s over 200 inches total!
Pro-Tip: Knit up pairs of I-Cords in similar lengths to achieve a uniform design on each side of your brain hemispheres.
Learn How to Knit an I-Cord: I have a video located on my How to Knit an I-Cord post that shows you exactly how to knit an I-Cord in detail. In just under 4 minutes, you will learn everything you need to know to make your brains with just two double pointed knitting needs and some yarn.
Alternatively, you may wish to use a Spool Loom or Embellish Knit, which are little tools to help you make up your I-Cord quickly! I have a new video tutorial that shows you everything you need to know to start knitting up brains without needing to know anything about knitting!
HOW TO ATTACH YOUR BRAINS TO YOUR HAT
Once your hat base is ready and a whole lot of i-Cord brains are knitted up, the fun begins!
It’s really helpful to have a mannequin head (or head-shaped item of your choice) available as you attach your brains, but it’s not necessary.
Brain Design: For your design, you’ll want to have a clear definition between the right and left hemispheres of your brain. Just weave a temporary strand of differently colored yarn down the middle of your hat to help keep track of each side.
What do your brains look like? The anatomy books show that each side looks somewhat similar, but maybe not completely identical, right? So, we just begin by tacking our brains into whatever curly brain coil patterns you chose onto our hat. To do this, use the same color yarn and a tapestry needle and lightly “sew” your brains directly onto your hat.
Since we’re using the same color yarn as our hat and brains, you really can’t see the yarn we’re using, so you can be pretty loose and not worry about it looking perfect. I like to attempt keeping each side somewhat similar by using identical lengths of brains on each side as I go in similar patterns, but no need to have them perfectly mirror each other.

Just keep tacking your brain coils to your hat until it’s totally covered. When your entire brain is full, you can either weave, or just tie and cut your yarn ends on the inside.
