I recently painted a 6 by 7 foot backdrop for an 80s dance. I wanted to paint a large mural this summer and I had the perfect opportunity. Here are some pictures. (that's my roommate asleep on the couch, she's 5'8" so you can see how big it is!)
Here is my apartment. Some of them look like they're straight from an 80s movie.
Here's my neighbor jumping in front of the background. I like how it turned out. :)
