Follow me eyes help

Hello! So I am making my first fursuit and I reached the eyes part. Can someone tell me what do u prefer to make the eyes from? I can't 3D print them and now I am stuck with too many options to chose from. I was thinking of using 1mm crafts Eva foam but it is too flimsy, but also I was thinking about using some normal plastic and mold it with heat gun. I am pretty crafty so I am not afraid it will too bad anyway but I would very much appreciate a seasoned opinion. Thank you^^
