I live in an apartment and dig doing large-scale art. Apartments, however, are usually a pain to paint and then paint to cover-up your awesome paint, and an especially big pain when you move around as often as I do. I do like having bright, interesting spaces, so I was brainstorming on creating a large art piece that I could maybe mount on the wall, or other types of removable decor, and the universe smiled on my with inspiration from one of my favorite blogs: Nest did a neat post on using contact paper to make wall decals.
