THE CHALLENGE:     Create a simple sorting system for a kid's playroom.   REQUIREMENTS:    1) Anyone (read: adults) who can't tell their Disney Princesses, from Dora & Diego, or Toy Story characters from Thomas the Tank Engine & Friends could easily help the younger children, who were just as clueless, put the toys away.  2) Having spent a lot of money re-doing the playroom floor, they wanted to use whatever containers they already owned.   SOLUTIONS:    1) Group toys based on the simplest common denominator, no matter which cartoon they originated from. Here, they were sorted based on function:  "Toys that make sounds", "Toys that have wheels", "People, Animals & Robots", "Large Lego's", "Things to use with Play-dough", etc.  Each each container was labeled with those titles on all 4 sides. 2) Containers were chosen based on their size and the amount of toys in a particular category they could hold.  The choices were made based on function  not fashion.
