Adventure Time: Finn's Hat + Pattern

Featured

The original pattern for this hat was made back when Adventure Time was a short featured on Nickelodeon, and then after it failed to do anything on that network, it made it's way to the internet. This hat is much more like the original "pilot" hat, where it's less of a tube with a face hole. This one has straps that you can tie underneath your chin.

The design for this hat came from my good friend Nate Little. However, he has been caught up in graduate school, and has had seemingly no time to write an Instructable. After months of kindly hinting and nudging him to write one about his hat design, and him never doing so, I simply asked if I could. Obviously, he said yes, and even helped me out. He even let me use his camera while I'm away at college. If you have the time, or like supporting your resident Mad Artisan, check out these links.

Step 1: The Pattern + Materials


The pattern is attached in PDFs below. When printing them, be sure to not "shrink to fit" or anything like that. The images are sized to 8.5 x11, and need to print in that size or else your pattern will be too small.

Some assembly is required with the pattern. The "Main Flap" piece is divided up into 5 or 6 different pieces and they need to be taped together, but I've made it so there are letters to help you align the pieces.

Once you get the pattern assembled, and ready to go you're going to need to gather some materials.
  • 1 Yard of Fleece (White or off-White)
  • Appropriate colored thread
  • Scissors
  • Pins
  • Sewing machine (optional)
  • Sewing needle (for the ears, or the whole thing)
  • Fabric scissors
Note: Fionna Variation
The only difference between Finn's hat and Fionna's hat is the length of the ears. If you want to make her hat, simply make the ears longer. I didn't include this in the pattern.

It's in Step 1. There are 5 separate pages to download at the bottom of the step, after the images and text.

Hi, i can't find the PDF link either... sorry... could you send them to me, please?

This is Finntastic! It took a bit for me to sew it (about 6 hours) because I don't own a sew machine (and it was the first time I sew), but the result is really cool!
It's money-inexpensive (hat: 1.80 euro), and the instructions are really clear!
So, thank you very much! :) here's the result:

Looks great! I'm really impressed you had the patience to sew it by hand, but that just means you'll love it even more!

if you put the right side out piece on the inside of the inside out piece, when you flipped it wouldn't the right side out piece be wrong-side out then? D: I'm confused
LegoBrickMaster7 (author)  allycat3126 months ago
The idea is to create a "double layered" hat. Which, once we flip it inside out there won't be any seams showing, and you just need to stitch up a tiny hole.

The tiny hole you leave is the key here. You end up flipping the hat inside out by pulling it through the hole.

It is correct to place the right side out piece on the inside of the inside out piece. This way when we pull it through the hole there will be no seams showing.

Hope that helps. :)

I plan on using this pattern for my Fionna hat I'm making for Halloween but when I printed out the pattern the forehead part looks humongeous! Does it end up looking alright or should I cut it shorter?
LegoBrickMaster7 (author)  allycat3126 months ago
There's a few pictures of people wearing it when it's completed, so you can judge for yourself. I would say it's a bit larger than I prefer. I think it almost sits at my brow, rather than a bit above it.

Hi, I'm making this for my son's (8 years old) Halloween costume and I was just wondering if I needed to make any adjustments in order for the hat to fit his size? Looks like this was more for an adult. Please let me know as soon as you can. Thanks!
LegoBrickMaster7 (author)  yangmama856 months ago
You would probably need to shrink down the size.

The easiest way to do this would be to shrink down the PDF when you print it by a certain percentage (probably 80-90%) in the printing options, and then checking the size of the "Main Flap" piece and how it fits around your son's head. I would recommend having about half an inch to an inch of extra paper when you wrap it around his head. Fleece is pretty stretchy.

Hope that helps!

FYI - I just layed the pattern out on 1/2 yard of fleece and it fits perfectly.
LegoBrickMaster7 (author)  gwenifae1 year ago
Awesome!

I'll be sure to add this to the materials step when I get a chance.
So is it necessary to have a full yard? or would a half-yard be sufficient? Or would half a yard be enough?
LegoBrickMaster7 (author)  dnacionales1 year ago
I really don't know. That might be pushing it.

The best thing you could do is print out and assemble the pattern, and size it up while you're at the store. Then you'll know for sure how much you'll need.

Sorry I couldn't be of much help.

does the backpack work?
LegoBrickMaster7 (author)  the potato1 year ago
No, it doesn't, but it should be pretty easy to modify the design to make it  a working one.

Hello~ I was wondering if it was possible to actually make the backpack into a functioning bag, like with a zipper and all...
Any suggestions with that? I wanted to make this for my friend for her birthday
Thank you^^
LegoBrickMaster7 (author)  straw18801 year ago
Sure! I've got a few suggestions.

If you're going to be basing your bag off of my designs and dimensions, all you should need to do is modify the light green 22" x 4" strip (the one on the top of the backpack). Get a zipper that's no longer than 22 inches, and attach it to the light green strip by cutting a slit, the long ways in the piece (before you assemble the bag). That should give you a zippered bag.

Other than that, I would recommend taking a look at what other people have done to make functioning backpacks. Etsy is a good place to look, and there's a few tutorials on youtube, too.

There's a good chance that using one of the other designs out there would result in a better functioning bag, since I designed mine to be used as a prop. It's pretty floppy.

Hope that helps!
Um, I have an unusually large head-I find it hard to find hats that fit me do you have any suggestions?
LegoBrickMaster7 (author)  CluainnFhada1 year ago
I think you should be fine with the pattern. It's pretty loose to start with, and fleece is pretty stretchy.

I would try to make one with the pattern, and if it doesn't fit, give it away to someone awesome. Then for a second attempt (if necessary) add an extra inch or so around the edge of the pattern when you cut it out (depending on how loose/tight the original was).

Hopefully that helps.

Awesome pattern! I'm really excited to make this. Is there any seam allowance, or must we add it ourselves? If there already is, how much is there? Thanks so much! :)
LegoBrickMaster7 (author)  Lollen1 year ago
It is included in the pattern, although it isn't marked. I should work on that...

Keep it between 1/2 inch and 1/4 inch, and you should be good.

Good luck!

how much felt did you use for the algebraic hat
LegoBrickMaster7 (author)  Tybunny211 year ago
I don't remember exactly...

If you get a yard, you should have plenty to complete the hat... and then some.

If you want to find the exact amount you'll need, print out a template and bring all the pieces to the fabric store with you.

How much fabric did you use for the backpack?
LegoBrickMaster7 (author)  Numbuh1Nerd2 years ago
I ended up buying 1 yard of each color, but I like having extra fleece around for various projects. If you don't want to pay more, and have extra, I'd recommend somewhere between 1/4 - 1/3 yard for each color.

For cutting the 14'' circles out, you'll have to make them into semi circles (since the fabric won't be wide enough), but you need to do that later in a later step anyway.

Hope that helps!
