I wanted to layer some artwork over my polka-dot walls to make sure the room didn't seem like a place you'd bring your stuffed animals to sip make-believe tea. After taking some inspiration from this post, I printed some images that I took in the U.K. in poster size at Kinko's (it was about $8 a sheet). I love that they're not glossy and that the resolution is a little gritty!
I pressed some metal clips into sticky tack to hang them. No holes in the wall and no need for a clunky frame!
