1108_Players_and_Pieces_15503You made it back, huzzah! Grab some pizza…or some carrots (gotta get in cosplay shape!) and let’s jump right intothe armor! What we are going to look at this time around is the armor that adorns Jaune Arc on his truly perilous journeys. Because let’s face it, in this world a guy is only as good as his armor! Yes, he may have someone saving his backside a lot…but that’s for another discussion.

The exact things you will need will include:

  • Craft foam
  • Contact Cement This didn’t work, see why below!
  • Pencils
  • Tracing paper
  • Exacto knife or another blade type
  • White glue
  • Worbla
  • Gesso
  • Heat Gun

Craft Foam

Craft Foam is going to be your key feature of use this time around. Learn to love it, and it will love you back!

Contact Cement

002739This is going to be essential in your armor making ways. Not only will it bond your foam together, but it will come in handy once you cover your foam in fabric. Yes, you heard me right. Instead of going the route of painting the armor, I am actually going to cover it in fabric. Where did I find this method? I came upon a video by YouTuber Emmabellish and my eyes lit up like the 4th of July. This was the method I wanted to use to get that clean look on Jaune’s armor without messing up when doing the paint. You will see what I mean when we get down to it (Hint: it doesn’t end well so I started over!)

The Accessories

Per the usual, you are going to want pencils to draw with and some ever so helpful tracing paper. This will be where you lay out your pattern on to for the actual build of the armor itself.

In my case, I had white glue on hand for gluing the armor together once I had it all cut out. I’ll explain more as I go along.

You will want to find a surface that you do not cut up completely and ruin for this. Take your exacto knife or other cutting blade and begin to cut out the shape of your armor. Go slow, and make sure you make clean edges. Clean edges will save you time in the long run of things.

Let’s Kick Some Armor Backside!

What we have here is the basic shapes for the shoulder pauldrons and the chest plate. The bottom part of the shoulder pauldrons are on the left, the upper in the middle, and the chest on the right.


I decided to go with the shoulder pauldrons in two pieces for a couple reasons:

  • One-cutting the exact shape of the shoulder pauldrons that Juane wears is pretty difficult. It is a specific shape, so you want to stick as close to it as you can. I found that doing two pieces helped me in this. Once it is put together, it looks fantastic.
  • Two-shaping a whole piece of foam in that style could get tricky. It would be easier (for me at least) to shape the two pieces separately on my shoulder and arm, Then, with them sized and shaped correctly, bonding them together.



Here we have the chest armor and the back armor. The two photos above show the general shape of the armors once they have been glued together using the white glue. From here, my plan was to move right on to covering the craft foam with the fabric I had bought.


That did not work. The contact cement dried on the foam decent enough, but once it dried on the white fabric, it left the color of the contact cement plain as day. This meant that it rendered the fabric unusable. This is why you should always have a backup plan!

My cosplay counterpart is making her Pyrrha armor out of craft foam and using Worbla to cover the foam. I took it upon myself to order some for my armor, and it’s already one of my favorite things to work with, even as a beginner! It is not hard to work with and once you get the hang of it, you’ll be working with ease.

20150609_185714_061915_085000_PMHere we have what the shoulder armor looks when glued together and then covered in the Worbla. The smaller pieces are the wrist armor which fits into the gloves that he wears. You can see that the shape once glued together is extremely close to the shape of the armor shown in the complete turn-around art. This is before there are added details to the armor, so it looks plain in the photo. I have added more details, which you’ll see in photos to come!

I’ve gone ahead and wrapped the chest and back armor in the Worbla as well, which you will see in the upcoming article focusing on the painting process. There is plenty more to go and we have only a few weeks until San Diego Comic Con, so be on the look out for the updates!

    1. Good question! The foam I used was your normal craft foam that you can buy from your local craft store such as Michael’s or Joann’s. You would find it in the crafts section, there are normally sheets of all colors for it that you can choose from. This white foam was in a roll. I purchased two of the rolls, just to be on the safe side, as this was my first experience with making foam armor.

      If you want to go with a thicker armor, you can use EVA foam, which you can find at your local hardware store. Think of it as the foam you put down on garages, or the foam that goes down on playgrounds. It’s thicker and you won’t need to worbla it if you don’t want to because it will have that stability.
