Hello I'm am trying my hand at cosplay and I wanted to make a helmet. After reading and watching some videos it seems EVA foam is the way to go.

My question is if there is a specific type of EVA foam to buy?

On amazon I found 100 1/2" sheets of this stuff called goamy EVA. Would that work?

Also at a local store there's a 6 pack of 2ftx2ft EVA mats for 20 bucks. Is that a good deal or naw?

Thnx
