While researching this month I came across these really good examples of using negative space. For the non designer, negative space is the unoccupied or empty space left after the main element shapes have been drawn by the artist. As these areas also have boundaries, they also function as shapes in the total design.

The guys at canva have found a few more great examples which they have talked about here:https://designschool.canva.com/blog/negative-space/
