Yes we do have something like that to now at the super market. A plexiglass wall between the salesman and the costumer, feels so weird.
And no if you want to breathe I suggest not xD but the idea for sure is interesting as a product of torture or mummification perhaps? xD
Thats something I made but its not real clay, its air drying mass. Though I prefer clay but that does need firing and to it doesn’t guarantee a success on your work. The firing is not possible at the moment those places are mostly located at a school that do the firing sadly and they are in holidays. But that works just as fine as an alternative. Im planning to do more of those relief kind of pictures I enjoyed to do it.
And you do also something creative?
