~ I¡¯m fixing up our basement and I¡¯m going to move down here with my pet but I be wondering how I could fix it up? I wanted to misery the walls in a rainforest scene because of the pets I enjoy, but I¡¯m not quite sure, does anyone hold any ideas? It¡¯s going to be my own private space as not a soul will leave me alone anywhere else. I resembling the Pirates of the Caribbean, maybe a seaside scene? Anyone have any pictures I could use as a stand for ideas or something? I really want some ideas. Oh yes! Light blue or white as the basis coat on the walls?

Thanks!!!
Answers:    What pets do you have?
How much money do you want to spend?
How big is the room?
I resembling the beach issue. You could get restrained wood floors or light brown runner (to reprent the sand). Paint the trim the same color, afterwards paint little starfish and shells on it. Then paint the walls light blue (for water). Add a dolphin, or make a payment fish or a surfer. You could get striped bedding (to look close to a chair you would find on the beach). You could own beach ball everywhere, and maybe own a small volleyball net going from one wall to the other wall. Frame swimsuits and dangle them on the walls.
Depending on what kind of pets you enjoy, i think rainfall forest should work
