Bunk Beds

so i have a teal bed room and i am sooooo bored with it. I have a surf theme that i got at target. SOOO i want to change it. Any ideas at all. BUT i can’t change the wall color. Or the fact that I have 1 full bed and 1 twin bed that can be bunk beds. I was thinking like a modern feel. Not so many patterns.

For many more for theme maybe http://1stupholsteryfabric.blogspot.com/
