Ohhh I did my daughter's room in butterflies and bugs, as she is getting older more and more princesses are coming along lol. But it's still mostly butterflies. I found some gorgeous butterflies made out of a tulle material at the dollar store. I hung them above her bed and they look like they are flying over it.
I also got dragonfly outdoor lights at IKEA I strung them in one corner of her room and it acts as her night light. I will take some pictures if you would like
I put a white picket fence (I just made it with wood and had it cut to size) along her back wall by the window. I strung flowers throughout it and then painted some dragonflies, bumble bees and butterflies along the wall.
