My wallpaper was inspired by this geometric pattern I came across while brainstorming for ideas. One thing I noticed upon completing the base of the pattern, was that while it does exhibit a degree of offset row by row, it still had a very strong vertical presence. In order to mitigate the verticality of the pattern I incorporated the overlapping ellipses to create a floral, petal-like design horizontally across the canvas. Finally I added some colors in specific moments to make the wallpaper stand out more.
