Make what you can and buy what you have to
If people want to use Foamex, that smooth skinned foam type board (no cardboard) I can suggest they go to any decent sized sign maker or exhibition stand design /maker for offcuts. I get all I can handle through my son, who's best mate gets tons of it.
Being entirely plastic, unlike Foamboard, it can't warp.
