I've found a video full of toy room storage ideas. There are a lot of different ideas in this one. Some are very inexpensive and easy to do. There are ideas for small spaces and larger spaces.
I really like the hanging pouches idea. They are easy to do and hold a lot of toys! I also really liked the under-the-bed drawer. It keeps everything tucked away! There are also a lot of different shelving ideas.
Watch the video and see if you have a favorite! Let me know in the comments!
