where can i get large sheets of cardboard. should i go to the supermarket and ask them for boxes or something. like can you even do that. i used to do that when i was a kid and making a science project in school or whatever but im no longer a kid and i dont think i can be that charming anymore. theres probably some regulation that says they have to throw everything away lest it be reused
@jk I'm a fan of buying something tiny from amazon which they always send in a box you could hide an aircraft carrier in
