Redecorating my room?

im redecorating my bedroom and the walls are a light lime green color. i want to add zebra accents and accessories, such as bed sheets (i already have a cute green comforter!) a paper lantern, trash can, and possibley a wallpaper border (but i want one where i can just stick it on myself...) so please give me some advice as to which stores i can go to to get this stuff for cheap! thank you(:
