Lines and Dots Crawling Around
This pattern is quit simple, and goes with all colors and on so many objects or clothes. I am inspired by an old drawing I did with a girl in pajamas who has a cloud over her, with a pattern reminding of this pattern. I have included a part of the drawing in the extra asset, so you can see what I mean.
I have also found 9 colors you can use as background, but as I already pointed out, the pattern goes with all colors.
