Turns out all you need is a shirt (check), freezer paper (check), and fabric paint (check), woo hoo!! Well, it also helps to have a Silhouette machine (no check on that), but I really only wanted to do a a mickey head on a onesie so I had my handy dandy exacto knife. All I did was print out a mickey head, trace over the design on the freezer paper and voila, I have a pattern. Then I put the shiny side down (psst, this is important!! otherwise the freezer paper may stick to your iron), and proceed to iron your pattern onto your shirt. After a coat or two of the fabric paint I was done!
I mean how easy is that?!
I used some old scrapbooking paper, printed out the labels, laminated them, and attached them to the boxes. In total, about a 10 minute (ok... maybe 15 with Charlotte helping me glue) job and voila... project #2 of the day is complete!
