Cozy Sketchies

I'm taking a very cool class about patterns & licensing and we've been given a semester-long project to manufacture an item (and its packaging) to sell in a pop-up Etsy site our class will be making together toward the end of the year. I'll be making cup cozies (I'm a barista, what else would I make?) and am presenting the idea to the class later today. Here are a few of the patterns I sketched out; there will be three total in the end. I want to keep them simple- they'll be two-color patterns, with only a slight difference in colors.

What do you kids think?
