This DIY is not only super cute but it's also super easy! Instead of using a frame, like in this pic, just tape up the actual paper to your locker. You could make a few of these and line the inside of the locker, like wallpaper.
What You'll Need:
Several different shades of lipstick
White construction paper or computer paper
Using several different shades of lipstick, pucker up and kiss a piece of construction or computer paper until the "canvas" is filled up to your liking.
