Last year I made a mold using plaster-impregnated gauze from a crafts store. That part was easy, but I had problems with the material for filling the mold. I made papier mÃ¢ché from newspaper and wallpaper paste.
The papier mÃ¢ché would shrink a lot when it dried, so the form was too small and a little warped. I tried using very little water in the mix and building up thin layers, but it always shrank too much and pulled away from the mold.
Is it better to use store-bought papier mÃ¢ché for the form?–or something entirely different?
