I wonder if you'll be willing to make:
-Liscense plates
-Alcohol labels
-Cereal boxes
-Graffiti
-Popcorn containers
-Packages like shown in the picture below
packages are a great idea, the alcohol labels, cereal boxes (im guessing for 1x2x2 prints), and license plates are a good idea too. i'll probably only make one cereal box and one license plate though, im not too keen on making multiple labels of the same thing so i can keep the same aesthetic for all of my prints
if you guys have any more great ideas tell me. i need some for the next time i host ;)
