$m@rt use of $p@ce!!! In that case know the limits of what a plastic suspended storage bin can hold. If it's filled with extremely heavy items and you can hardly lift it or it appears to be bowing at the edges and bottom when placed then it's definitely a good idea to lighten the bin to prevent this from falling. Obviously use your best judgement. ;•]
Bungee cord ball storage makes different balls easy to access and find. Horizontal slats store tall items and plenty of shelves hold onto other toys. A tennis racket gets it's own space using two nails to support either side of the handle and it lays flat against the wall.
