You can design dishes, too!
Dishes by Nina Levett
I've got a thing for dishes and linens, which I may have inherited from my mom. These may not be things that immediately come to mind when you think "graphic designer" but it can be part of your job description! Take it from John Beach, who does this sort of thing all the time for Starbucks and others.
Look for "Surface Design for Consumer Products" with John this summer.
