I adapted some of the colour codes that appear in other processing designs to create a less simplistic block-colour background. I also lowered the pattern separation number to make the result appear slightly more intricate.
After browsing through wallpaper books in the Te Aro library, I came across an image in 'A Popular Art: British Wallpapers 1930-1960'. This design is a vague replica of that picture. I was unsure of how to create a loop so that the lines in the background could easily be repeated.
