ideas ?!

Myranda • April 14, 2016 ❤️ our first little monkies 🐒🐒
i'm renting , and was told i cannot paint. i wanted the girls' room to be pretty and fun! we are doing a butterfly theme, and the walls are tan :/ 
i heard something about removable wallpaper, but i don't know anything about it.
any ideas of what i can do ? i feel tan is so boring for girls lol.
