I’m a sophomore starting my first year of fashion design what bags do you recommend for carrying all of the rules and other supplies I have a granny cart but that might be too bulky to move around campus I was also thinking of getting one of theses small crates with wheels but I have to carry around those super long rules and don’t want someone to snatch them while I walk to class
