Over the several steps listed here ill demonstrate a handful of good techniques when working with EVA foam for the new and experienced cosplayers or costume enthusiast. Ill be demonstrating cutting, forming, edging, gluing and a few other tricks. I learn better ways and new techniques every time I do a costume so check back often for improved or new tricks and examples.

Poster card/ card stock
Xacto blade/Razor knife
Hot Knife
Heat Gun
Soldering Iron
High temp Glue Gun

I'm a newbie when it comes to armor but I decided to give it a try! My dad have a lot of tools and I bought some good foam recently, I will certainly start tomorrow!
I found a "modest" armor in Monster Hunter tri that will be fun to make!

Your article is very clear, English isn't my first language but I can understand it very well! :)

Your are welcome! Thats what im here for. If you have any questions feel free to send me a message on facebook!

hello, i apologize if this has already been asked but i was wondering about the clear helmet you are wearing in the picture. how do you make that or how did you go about it? i was hoping to do a Mr. Freeze soon with the clear doom over his head but not sure how to approach it. any tips?

Thank you so much :)

Hello! No worries im sure it got buried some where anyway. Here is the link to the exact "helmet" I bought:

I simply just used my dremmel to cut the neck opening wider. also add several PC case fans for circulation and anti fog spray other wise it will fog up, you'll asphyxiate and you will die. :)

thank you so much! and i promise i will try not to die XD

Great walkthrough, thank you for taking the time to type it out! I was just googling "EVA foam" and your link was the first one that popped up, how fantastic.

Quick question regarding the different types of foam featured in your walkthrough: what's the texture like on the underside of the fatigue mat EVA foam sheets? I'm eyeing the 0.25" pieces for example. My current project requires a smooth finish like craft foam but fatigue mats will have a textured surface (for obvious reasons). Do you know if the underside is smooth or textured?

Towering Props (author)  TiffanyC31 month ago
Hello! Thanks for the support! As far as i've come across all EVA has a textured side and a non texture side which is smooth. So yes it should work just fine for what you need.

Thank you so much for your fast response! I can only hope my armor turns out as amazing as yours. Fantastic tips all around, I can't wait to get started!

I've purchased 3 thicknesses of foam so far: 0.25in anti-fatigue roll mat, 3/8in 4-pack tiles and 3/4in 6-pack tiles.

Both the roll mat and 4-pack of 3/8in tiles are textured on one side and flat on the other.

The 3/4in tiles are textured on both sides, however.

Thank you for letting me know! I purchased the roll (0.25") and it is indeed smooth. Good to know about the other sizes in case I need them for future projects.

Hi would it be okay to ask a question regarding putting a glue stick from heat gun on eva foam? i am having problem after glueing it on velcro to eva foam, after several use of glued velcros in eva foam the velcro will later easily removed from it after using. what should i do or can be done?

Thank you!

This site details straps well and also mentions the same thing Towering Props did:

You can also hot glue velcro to armor, but I would highly recommend that you sew it to a piece of nylon webbing first. Hot glue doesn’t grip well to velcro and will easily pull up. If you sew it to a section of nylon webbing first, then it will have something to grip to.

Beat me to it! Thanks for commenting!


Katejina nailed it below. Adding a backing to the Velcro will allow it to stick much much better to the eva foam!

Hi Towering Props. :) I only just (not even a week ago) discovered armor with Eva, and was wondering, should I buy thin or thick foam for some Skyrim armour? It costs too much to buy both, as I only have a part time job.
Towering Props (author)  OceanWhisper5 months ago
Hmm thats tricky... depends in the armor your looking to make. Say if you want to make deadric i would reccomend the rolls but if you wanted to make dwarven i would say the tiles.
Thanks anyway :) I eventually just spent the extra $10 to get a roll of the thin foam. I figured that I could just layer it. I've made one gauntlet so far :D also, do you know if I can make acrylic paint look more 'metal'? I'm not able to buy spray paints of any kind. Thanks

4 months late, I know, but... I've been working on a costume and I've found that Martha Stewart's line of acrylic paint works really well. There are a variety of "metal" colors available. Best selection I've found is at Michael's.

If you're looking for something similar to Skyrim iron or steel armor, you can mix the Sterling and Gunmetal or experiment with some of the other available colors. Hope it helps.

Hobby Lobby is owned by terrible people. You should use Michael's instead :)

Support companies who deserve it, here's the link so you can replace the Hobby Lobby one.

I would like to make some pieces look like leather. Any suggestions?

Towering Props (author)  diane.teeter.51 month ago

Hello! Hmm yes well leather is one of those materials that only leather looks like leather. I have had minor sucsess using really thick craft foam and putting mutiple layers of plasti dip on it. Krylon makes a paint color called "Brown Leather" and it looks kinda convincing. I would recommend that technique if your attempting a leather look with EVA.

I would like to make a fully round helmet, a ball shape with a diameter of about 35cm. Do you think this would be possible with EVA foam? Or should I try a papier-mâché solution instead? I'm going to give it a try anyways but tips are always welcome :-)

Towering Props (author)  Lubaaas2 months ago
Hey! Totally possible what you need to do is cut triangles out of the foam in order to have it round it. Just experiment and use that heat gun and it should be possible!

That's a great idea, thanks!

hi ToweringProps, do you know if hot glue will hold button snaps, and what about attaching Velcro? do you think I'll have to use superglue or hot glue to make it stick? cheers :)
Towering Props (author)  OceanWhisper2 months ago
Hey! It will hold with the hot glue but not for very long. Hot glues adhesion is based on surface area and theres not much of it with a small snap. How ever if you attach a snap through a scrap piece of frabric then glue the fabric to tje piece itll last much longer. Also using a 2" square of velcro with a snap in the middle you get the best of both worlds. The friction of velcro and the security of the snap.

hey again :D I hope you had a fantastic Christmas, and soon a happy new year. I have a question, what's a good way to attach shoulder guards to a corset-style piece? would Velcro on the inside of the foam attaching to straps work? ( dunno if that even makes sense? XD ) thanks
Towering Props (author)  OceanWhisper2 months ago
Hey! Thanks and a happy and safe new year to you! That's honestly what I would recommend. Might have to experiment a little bit but a solid strap across your shoulder and a solid strip if Velcro along it attached to the foam should work just fine. small buckles with elastic are also a good alternative if it doesn't hold like you want it too.

Hey I've been planning to start an armor but I'm completely boggled for a way to make the helmet with some short of visor as the rest of the armor is quiet basic

Towering Props (author)  TerraP13 months ago
Forgive me for not quite understanding but what are you trying to do? Do you want the shield that covers his eyes to be transparent so you can see? Or you aiming to add a visor?
keithpurdy913 months ago
You put in capital letters to not paint the inside of the armor. But i bought the multi colored foam. What is your reasoning for not painting the inside?
Towering Props (author)  keithpurdy913 months ago
Unless you seal it the paint will chip and sweat off and get all over you. In the long run its just a waste of time and money. Unless its visible from he outside theres no reason to paint it.

Hi, could you possibly give me some more detail on how to make a harness? My costume needs one, but I can't quite figure it out

Towering Props (author)  BenS84 months ago
Basically what your creating is an H harness just out of stuff you can get at Walmart like buckle straps and luggage straps. The 1" straps you can get in the camping section at Walmart and the 2" buck straps you can get in the luggage section. buy cutting the 1" straps the the right size you can easily create an H harness for a couple bucks.
here's a picture of what a H harness looks like. (

Ok, Thank you, and by the way, your instructable is really helpful so thank you again!

Awesome instructable! Thanks! I wish I'd seen this before making a Destiny costume for Halloween. Well, there's still Fanime.

I need to make a belt and I was wondering what would be the best material. If I should use foam or something else. I was thinking foam would be better. If it helps at all, I'm cosplaying Tsubaki Nakatsukasa from Soul Eater.

Towering Props (author)  AlwaysYoursx3334 months ago
Yah i would reccomend the roll mat because it will be long enough to have the belt be one piece. Rather then glue mutliple pieces out of the tile foam.
