Everyone's current favorite play storage area is the costume wall. All costumes and accessories are hung with my favorite organizing tool that I've literally mentioned in every blog post so far, The Command Hooks! They're hung at kid height so they grab whatever they want and get right to it.
The bottom row is for the costumes and the top row is for masks and other accessories. This area does get messy pretty easily so I also have a basket on the floor (not pictured) for the kids to toss things into if they just can't handle hanging items back up on their hooks (which we all know happens more than not).
This is another great example of how being organized allows for more spontaneity, creativity and most importantly, fun for all of us!
