Adventure Time: Finn's Hat + Pattern

 by LegoBrickMaster7
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.

FYI - I just layed the pattern out on 1/2 yard of fleece and it fits perfectly.

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) in reply to dnacionalesJan 25, 2013. 11:40 PM
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) in reply to the potatoJan 23, 2013. 1:11 PM
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) in reply to straw1880Dec 14, 2012. 10:21 AM
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) in reply to CluainnFhadaNov 21, 2012. 2:22 PM
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) in reply to LollenNov 18, 2012. 10:00 AM
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) in reply to Tybunny21Aug 4, 2012. 2:24 PM
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) in reply to Numbuh1NerdApr 4, 2012. 6:11 PM
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!
