Brain Slug Inspired Headband

Hey there, guys and gals!


This post today comes from a project that I had completed over the summer which I really enjoyed. San Diego Comic Con was coming up and I wanted to come up with a variety of pieces to wear for each day, just for fun. I really enjoyed seeing other yarny crafters’ ideas, showing off their skills and love of pop culture. You can check out my recap with this post! One of the projects that I myself had put together was a headband that looked like one of the brain slugs from Futurama. I wanted something simple that I could put together for the event that wouldn’t be too obtrusive and I think that this one fit the bill.

It’s a nice quick project and I think you’ll enjoy it. With the convention season off to a strong start (WonderCon, in Anaheim, CA, was just this past weekend!), perhaps you’ll be looking for something simple but also nerdy and funny. So enjoy and let me know how it turned out for you!



4.5 Crochet Hook
Worsted weight yarn in a green color
(I used Big Twist Premium in Sprout)
White felt
Green felt
Permanent marker
Hot glue gun (I’m sure crazy glue would work as well)
Headband (find a similar set here)
A small amount of poly fiber fill for stuffing


Terms Used (US):

sc = single crochet
st/sts = stitch/stitches
trbl = treble crochet
sl st = slip stitch
ch = chain


Your slug is going to be done in a couple of pieces that will be assembled together. The pieces will consist of the Body, the Base, and the Antennae. We’ll start with the Body since it’s your largest piece of the puzzle.



With your yarn, start with a magic circle

Round 1: Ch 1, 12 sc into magic circle. sl st into beginning ch 1
Round 2: Ch 1, 2 sc into each stitch around, sl st to beginning ch 1
Round 3 – 13: Ch 1, sc into each stitch around, sl st to beginning ch 1
Bind off


Start with another magic circle
Round 1: Ch 1, 12 sc into the magic circle and sl st to the beginning ch 1
Round 2: Ch 1, 2 sc into each stitch around and sl st to the beginning ch 1
Round 3: Ch 1, sc into each stitch around and sl st to the beginning ch 1
Do not bind off


You can begin attaching the Base to the Body with a sl st to connect the pieces. Ch 1, sc into the sl st, and single crochet matching the scs from each piece, creating the seam between the two pieces. Work half of your seam, and then start stuffing your Slug. It’s harder to stuff the body and THEN try to seam your pieces together, so at least get them lined up and halfway stitched together, and then start stuffing! Like so:




Once you’ve stuffed your Slug and feel good about its fullness, then continue to finish the single crochet seam and sl st to the beginning ch 1. Don’t bind off

This will cause a small pucker to form at your base and will give you the launch pad for the little tentacles, which we will be working in scallops.

Ch 1, skip 1 stitch, 5 trebel crochet into the next stitch, sl st the next, sk st, 5 trbl, and continue to the end of the round, sl st and bind off.

These will form your little undulating “legs” for the Slug!


Now let’s put some antennae on this guy!



(You’re going to make 2 of these)

Leave a small beginning tail and ch 7, then 3 sc into the 2nd chain from the hook
Sc back around to the beginning chain
Bind off with a bit of a tail and stitch it into the top of your Slug, wherever you’d prefer. Tie your ends into a nice knot and tuck your ends into the Body of the Slug!



He’s looking more alive now, but now he needs an eye!



Remember in the materials list when I said you need felt? The time has come! I’ll give you an approximation of how big the rounds of felt should be, but I literally just used some appropriate lids to trace circles for them. You’ll need one circle of white felt and another circle of the green felt.

Let your glue gun heat up while you’re tracing and cutting out your felt if you’re using one. I felt a glue gun would be the most effective option, but you can go with the type of adhesive you feel the most comfortable with or have laying around the house.

The white felt circle will need a dot in the middle of it, which you can draw in with the permanent marker. This is going to be the eye of the Slug. The green one will be going underneath the Slug and help you keep it on the headband.

Glue your white felt onto the middle of the body of your Slug where you’d like the eye!
Take your Slug and place it on the top part of your headband where you’d like it to go. In the show Futurama, which directly inspired this project, they’re situated off to the side of the person’s head, as you can see in this image:



And that’s what I went with with my headband, though you are free to place it where you’d like. Once you’ve picked where you want it to go, lather up some glue on the bottom of your slug and some on your green felt and sandwich your headband between the 2 pieces. It’s slightly chunky for the headband on its own and the felt on the bottom gives it extra stability. (I’ve suggested green since it would more readily blend in with the green of the Slug itself, though you could just use another piece of the white felt and make sure it didn’t tuck out too far of your Slug body.


Once the glue has cooled down and/or dried, you’re good to go! You’re ready to join the Brain Slug Party! I hope you like working with this pattern and I’d love to see your work, so feel free to tag me on the Internet!


Side fun:
Here’s a shot of me at San Diego Comic Con in 2017 wearing my Slug while working on some other projects in my downtime.


Conventions can get wild and it’s necessary to decompress from the madness! I’ve shared the patterns for the projects in the past here on the blog. I’m holding a pair of Ewok inspired ears, which you can find on my Crochet Animal Headbands post, and on the table is a pair of gloves worked up from my pattern Granny Gone Chic Gloves!



Until then,
