Sometimes it’s your only option, but really try to not use your bedroom as a storage room. The bed is a place for sleep and rest, not storage. Again, this will only make your room messier and cramped. Add paintings, curtains, light fixtures; make your bedroom a beautiful place to be. Shelves should only hold pictures, piggy banks, and decorations. The closet is for clothes, shoes, and accessories only.
If you keep your donations box in your bedroom, you need to move it. Since the bedroom is off limits for storage, the best alternatives are closets, cabinets, attics, and basements. Boxes used for storage can make your bedroom seem very claustrophobic. Storing things under the bed makes hideouts for spiders. Storage is a necessity, but if at all possible, keep it out of the bedroom.
