heres how to do wax castings into like gold or something, first buy some wax, if you have no money, then fuck, improvise if that's the word. get some used candles, i dunno used wax shavings whatever, i have done castings from soap but wax is best. second, carve with a knife. best use a shartp sharp knife. tots of practice, whatever.
3rd sand it maybe i dunno.
4th, cast them how? i dunno no one taught me anything. send the away, if they don't steal or axidentaly break your ideas it's all good. might cost you a few mneynumbers tho but lie magic they will come back from wax to whatever metals you have money for.
this is how stupid loans companies are, they are unable to loan you fake made up printed out o thin air completely made up init?kindathing money numbers in exchange for real high quality works of art. i have explained, loo i have plenty of high quality waybetter than anyone else's art i could be makin way better machine made art to sell for cheap to make us all billionaires works of art. in short, real things to sell that money can't even buy unless you want it to works of art for made up printed out of thin air moneynumbers, and they are like no paperwork. i dunno.
and yes i do clean my room once in a while but my work involves real work involving making a mess when i have no room to make anything.
