I needed my costume by the 20th this year, and my original costume plans were way to grandeur to complete in one weekend. I went as Finn, from Adventure Time last year, so I figured I would just give my costume an update. I really liked the episode "Finn the Wizard" and the cloak ("dress") he wears throughout the episode seemed like an easy addition to wear over my previous costume.

The pattern making and assembly for the whole thing took about 4-5 hours. Making the pattern was the hardest and most time consuming part, so it shouldn't be too hard.

Step 1: Materials

You'll need a few things to complete the project:

Measuring Tape
Marker
Fabric Scissors
Sewing Machine
Pins
Thread
Purple Fabric (3.5 Yard Minimum)
Yellow fabric (8 Inch Square)

I got my fabric from Joann, which was a micro fleece, and used a 50% off coupon from their smartphone app. In total, the whole project cost me 20 dollars.

Step 2: The Pattern

The pattern is adjustable for your height. I'm somewhere around 5' 8", and the measurement from the top of my shoulders to the ground is 56 inches. Anyone shorter than me can just adjust the size later, when you hem the bottom of the cloak, but for anyone taller you'll need to tack on extra inches to the long vertical measurements in the pattern. You'll also need to get more than 3.5 yards of fabric. Mine BARELY fit on the 3.5 yards I got.

The hood and sleeves should be left alone, as they will fit almost any body type.

Also, it's important to note that the only "full size" object in the pattern is the star, and that I've taken into consideration room for seams with the measurements given on the pattern. You'll also notice grayed out sections on the pattern. This is an opportunity for you to fold your fabric in half while you cut out the shape (making it more symmetrical, and easier).

Step 3: Cutting the Body

I folded my fabric in half (hot dog style), then pulled it so the top fold so it was 25 inches in length. This way, we won't waste precious fabric by cutting a huge hole out of the middle. Both the front and back body sections will be traced out and cut over this top fold.

Be sure all the measurements are correct before you start cutting out the pieces. I kinda messed up the bottom on the front piece, but it's fixable later when we hem the edges.

Step 4: Cutting the Sleeves and Hood

With the little remaining fabric, start out tracing the sleeves. I doubled up the fabric, so I would only have to trace/cut one, but would get two pieces. Once the sleeves are cut out, find a spot for the hood, which we also need two of.

Step 5: Assemble the Main Body

Start by laying the front and back pieces on top of each other, lining them up at the 6" shoulder bars. Remember to have the side with sharpie facing outward right now, so when we flip it later, it will be hidden on the inside of the cloak. Pin the shoulders, and sew.

Next step is to lay out the front and back pieces on the floor, so the seams from the newly sewn shoulder bars are sticking up. Grab the sleeves, and pin them into the appropriate sleeve holes on the body. Pin the sleeves to the body, and sew. Don't do sewing under the sleeves, only where they meet up with the front and back pieces.

Fold the cloak in half along the shoulders. Remember to keep the seams facing outward. Pin up along the side of the body and the underside of the sleeve. Do this for both sides. Once you have it nicely pinned, sew up the sides.

Step 6: Attach a Hood

You should have something resembling a cloak. All we need now, is the hood.

Place the two hood pieces on top of each other, and make sure the marker sides are on the outside. Pin the along the large curved edge, and sew the two pieces together.

The pointy parts of the hood get pinned to the front piece, and the small curves get pinned to the back piece. Be sure to double check you've got the hood the right way before you sew it. I've made the "inside out hood" mistake before.

You can take the opportunity to flip the cloak so the seams are hidden away on the inside, and give it a test fit.

Step 7: Add a Star (or Many)

I was in a rush for my costume, but if you're feeling ambitious you could potentially be one of the "wizards in training" with the cloaks completely covered in stars. That would be impressive.

I borrowed a small scrap of yellow fleece (you only need an 8 inch square), and traced out the star pattern on it.

Cut it out and pin it onto the cloak in a position to your liking. I tried mine on with the star pinned in place, just to be sure it was in a good spot. I used my machine to sew the star on, but you could potentially do it by hand.

Step 8: Hemming

Here's the step where we make everything look nice.

I started out by pinning the bottom edge of the cloak while I was standing, with it on. Once I got a few good placeholders in, I went around the rest of the bottom, and then sewed around the edge.

Do the same for the sleeves. Wear the cloak while adjusting the sleeve length, then take it off and finish pinning and sewing the edges.

The hood is the trickiest part to hem, but it's the same basic idea. Fold the edge under, and remember to do the front parts so the end in a point.

Step 9: Finish!

If you're going as Finn The Wizard, you'll want to check out my other Instructable on making his hat.

But you could very easily just go as a wizard student, or maybe even make yourself an awesome beard to go along with the cloak.

Hope you enjoyed the read, and I'm always open to comments and feedback.
