Random squares are my go to doodle whenever I am confused on what pattern to create or when I don't find anything around me to inspire a pattern.
I really had no mental image or idea in place when I was making this illustration so it just had to be the default squares.
Then I added a lot of colors so that it looks like something I planned.
I didn't, it just happened. *inserts deep quote about why the best things happen outside the comfort zone*
