Let's see, we have those large plastic shelving units that are really made for garages and workrooms that you can buy at Walmart for about $10.00 for all of the large toys that sit or stack nicely, like all their remote control vehicles, musical instruments, little people garage, pirate ship, etc. The tallest items go on the top shelf, since there is nothing for them to bump into. Then we have one large toy chest for everything that can easily be thrown in. Then we have a large 3 drawer plastic unit (also from Wal-mart) for all the medium sized toys. Top drawer for younger son's toys, middle drawer for older son's toys, and bottom for flat items, like puzzles, and story reader stuff. Then we have a cloth bin storage unit, 9 bins total, for all the little stuff. Each bin has a theme, ex. star wars action figures, super hero action figures, little people, dinosaurs, happy meal toys, etc. We have a cloth pocketed book shelf that all the books can easily be slid into (easier for younger clean-up than a traditional book case). We have a cardboard 'mailbox' unit (like the kind you see in schools and offices) mounted on a shelf on the wall, for all my older son's school supplies, markers, crayons, and expensive toys that the little one shouldn't touch, for fear of him breaking, as well as some of the smaller board games. We have a low stacking closet shelving unit, that holds all the board games (bought at K-mart), and we have two large wire shelves mounted high on the wall for all the stuffed animals. So, no one organizational unit for us. It takes a lot of units, but they are cheap individually (none of them cost over $15), and they make clean up sooooooo much easier now that everything has a home. Good luck!
