Any advice on how to organize a small bedroom?

I'm a 16 year old girl, almost 17 and I love redecorating (inexpensively) and cleaning my room. But I have such a small room that I get frustrated when I make new makeup purchases because I don't know how to store my things. I'm thinking of draping some different patters on the wall and putting up some decorative mirrors to make my room my own until I go to college. But any organizing ideas for hair/makeup/body products and how to maximize space? Thank youu :)
