Building this pattern in Illustrator began as simply an exercise to become more competent drawing with vectors. I think I've accomplished that! The thing I love about working with pattern is that you need only draw one little square, and from there you can create a seemingly endless series of interlocking patterns and color schemes that have completely different looks and applications. This pattern is also a preliminary investigation for an animatic illustrating Charlotte Perkins Gillman's short story, "The Yellow Wallpaper". The wallpaper described in the story is horrifically over-embellished, and it's nauseating shades of yellow literally drive her insane. Nothing is more fun than coming up with intentionally ugly color schemes! Get ready to go blind! But first I made a few pretty ones.
