Dinosaur Hoodie (Sweatshirt)





Introduction: Dinosaur Hoodie (Sweatshirt)

Make this cute jacket in an afternoon!
This project is a pretty simple design: a hoodie sweatshirt with a row of spikes going down the back.
It was inspired by a similar one I saw in a store...but that one was toddler size! Little kids get all the coolest stuff. So I decided to make a big-kid-sized one for my sister for Christmas. It's just her style and if I'm lucky I can "borrow" it and wear it myself.

Step 1: Materials and Equipment


Sewing Machine
Nice Sharp Scissors
Seam Ripper or Small Knife
Sewing Pins
Fabric-Marking Pencil ( I just used a white colored pencil)


Piece of Cardstock (for pattern)
Plain-colored Zip-up Hoodie Jacket
Fabric (I find that using fabrics with siilar textures works best)

Step 2: Splitting the Hoodie

There is almost always a seam down the middle of the hood. Start by ripping that out using a seam ripper or small sharp knife (which is what I used because I don't have a seam ripper).

Then fold the hoodie in half, and cut down the middle of the back. *Be careful to line the sides up or later on your row of spikes will be crooked.


Step 3: Making the Spikes

First decide on the size and shape you want the spikes to be and cut out a pattern (cardstock works well).

Next figure out how many spikes you will have. This depends on the size and spacing. Mine are about 3 inches wide at the base and will be about 1 inch apart, so I estimated that I needed 10 spikes. (*Remember that they will be a good deal smaller after sewing. 10 ended up not being enough, so I had to make extras.)

Now trace your pattern onto the fabric and cut out twice the number of spikes (*2 sides to each spike).

Pair up your triangles and lay them face to face (wrong-side-out), then sew the top two sides- but not the base. Pin together if necessary.

When all this is done, turn the little triangle pockets right-side-out and you're ready to put it all together.

Step 4: Putting It All Together

Fold the hoodie over wrong-side-out and place the spikes between the two layers, pointing inward (line up the base of the triangle pockets with the edges of the jacket) and pin in place.

    i want to do this... work desk, here I come!!!!!

    This is great! I'll try to make one for my kid

    This is awesome. But since I can't sew(but it'd be manly if i could) I will ask someone i know can to do it, like my mother :D nice instructable!

    Pfft, manly men learn to sew. =D

    Awesome Instructable.

    "Sewing isn't hard. Just think of it as woodworking with very soft wood." (That's the approach I took for my T-tunic, and it worked better than I expected.)

    Yes; it's a very nice bit of design. One minor tweak the completely changes the interpretation of the garment... and not just another set of cat ears. Definite points for creativity, and for not going overboard.

    I was going to make a cat, but you killed that idea :(

    Whups. Please go ahead; I own a cat-eared hat, so obviously I'm not against them -- it's just that I've seen lots of folks do it badly.

    (I'm not wild about the hat I've got, actually -- Plus is that it's a nice furry fabric and the interior of the ears is a suitable contrasting fabric, minus is that the ears aren't really placed correctly for an anthropomorphic cat, and the hat doesn't cover my human ears.)

    I don't know whether you saw the Japanese cat-ears that shift their expression in response to a set of electrodes on the user's forehead, trying to respond to the wearer's emotional state or at least to some signal people could use to control them with a bit of practice. The motors were a bit noisy, but the idea was interesting enough that I've sometimes pondered what it would take to do a simple version, possibly entirely mechanical with control cables down to inside a jacket's pockets.

    And I'm *still* trying to figure out how to make a tail that moves properly. I've seen animated dog tails, but cat tails are more expressive and may heed at least one more set of "tendons" to get the proper degree of control.

    That's cool! I think I might put wires in my (black) cat or other animal of sorts to hold it's tail up. My choices are as followed: Bear, Wolf, Cat, Mouse. Anything else you would suggest? It is a plain black hoodie, and I have many colors of fleece-like fabric including black. I can't find an ear pattern online. :( so i guess i have to make it myself. My ears in my vision of it are 3-D. Any help?

    i like the bear idea since its a black hodie but if u have white fabric you could always make a koala or a panda bear!

    I had to get rid of the jacket :( It got too small. I grow like a weed.....

    Definitely 3D ears.

    The simplest version of cat ears would be two triangles attached along one edge -- think tetrahedron (d4, if that helps) where one of the sides is actually part of the hood and one (the front of the ear) is open. Altering the shape of one or both of the triangles could round off the ear and otherwise fine-tune its shape. You might need to include something that would stiffen the ear to help it maintain its shape.

    Experimenting with scraps, and/or with paper, might be a good way to figure this out.

    Have fun -- and if you come up with something you like, please do post it!

    maybe a panther would be cool!

    Maybe I'll put something inside the ears to make them 3-d. I could also use fabric stiffener... Thanks for the help!

    Thank you for the compliment. : )

    I agree. My dad sews (though not clothes, he can't follow a pattern to save his life). The guys at his shop made fun of him until they saw all the cool stuff he made. : )

    Hmmm, wondering if the "spikes" might stand up a bit better with **batting between the layers?
    **Batting is what's used in-between quilt layers to give it that little bit of "cushion".


    It's cool projects like this that make me excited to re-learn how to sew (haven't sewn since Jr High & am taking sewing classes next month at the local college). Will post a pic if I can figure how to make this.

    BTW, I totally agree with you... Little kids do get all the cool clothes ~~ until now ;0)

    Love your Dino Hoodie 'ible!!


    Wow thx for the 'ible! Im thinkin' of dino hats, shirts, and much much more!!!
