That sounds like an awesome amount of decluttering!

We decluttered our daughter's bedroom (with her permission) and gave it a makeover while she was at sleepaway camp. The difference is huge! She has said over and over how much she loves having less toys, and having more room to play. Some things are in storage for possible rotation for now, but they may end up getting donated as well.

We cleared out a ton of picture books now that she's into chapter and middle grade books, too, and my spouse and I got rid of some of our own too. I need to aggressively go through my craft stuff next, I think.
