I actually collect lots of things! It's a really fun hobby, though it can take up some space. I have a lot of little boxes of stuff in my room: they mostly contain things like shiny rocks, pinecones, coins, keychains, small toys and random things I have found somewhere. My favourite items are displayed on my desk, like a tiny knight figurine (it's like one inch tall) that I found at school. I also have some really cool rocks, for example a heart shaped one I found in Norway a few years ago. Oh, and a tiny purple Chinese dragon that's even smaller than the knight!
I also collect art supplies (because you can never have too many) like notebooks and nice pens. And I collect stuffed animals! I have a LOT of stuffed animals. I don't think this is all, but it's all I could think of now. I really like it!
