Use large, plastic storage boxes for organizing closets, sheds, garages, basements and attics. Storage boxes are commonly used in areas that are damp or have varying temperatures. They are ideal for these settings, since the plastic is non-absorbent, and lids fit securely around the edges of the containers. Contents of large storage boxes often include holiday decorations, blankets, tools, clothing and toys. Other options for using large storage boxes include beach vacation supplies, truck bed organization and camping supplies.
