Loki Chest Plate Craft Foam Guide - The picture on the bottom IS NOT MINE, it is just for reference.
Materials used to make mine:
- Craft foam
- Mod Podge
- Paint/Spray Paint
- some black clothe
- Exacto knife
- 120 grit sand paper
I used two layers of normal craft foam to make the main black part of the chest plate. I have no idea how the movie designers made the chest plate and how they keep it in place so I’ve basically just been using the jacket to keep the chest plate in place until I saw Khaos Kostumes idea. The put strips of pleather on three of the edges and sewed it into the costume so it’d stay in place. I only put a strip on the bottom part of the chest plate.
(and I still have no idea how you’d wash this costume…. suggestions anyone XD?)
Keep in mind, the biggest problem is making the chest plate big enough to cover the chest area but small enough so you can still rotate you arms forward without being restrained by the chest plate. I didn’t think about the need for forward arm movement the first time I made the chest plate and had to cut off A LOT off the edges. I’ll show you my crappy first version in another post…. It’s actually being use on the back of this newer nice chest piece as the second layer.
I used two layers of craft foam so I could sandwich the strip of fabric inbtw and it could be sewed onto the rest of the clothes.
I cut out the gold part of the chest plate from craft and hot glued it on top, I used the blunt back end of my exacto knife to impress the lines into the craft foam.
After the the craft foam is all together I would heat it up and curve it up like the chest piece is. Then paint layers of gesso on it to thicken and strengthen the craft foam. I did at east 10 layers. I then used 120 grit sandpaper to help smooth out the gesso and used painted it.
I didn’t paint it gold first because I wanted to prime the whole piece together so it’d look smoother and I had to paint the whole piece black first and then use masking tape around the center part so I could spray paint it gold.
I painted layers of mod podge onto it last to seal the paint and give it a smooth finish. I did at least 3 layers. The mod podge dries clear and feels plasticy. Thinner and more layers of anything will always give off a smoother finish than less and thicker layers.
I usually only work with craft foam although I have air dry clay and bake clay sometimes. I like to use the cheap but good methods so if you want to make an actual silicon mold or resin, I’d suggest looking into Khaos Kostume’s guides or googling around. For those who don’t have the money, skills, and patience to work with these more expensive materials I hope this craft foam guide helps you! Craft foam is my go to material =] Cheap and easy to work with!

Will post up a supplies pic after and how I made the arm guards with Craft foam too.
