other than furniture such as my bed, bookshelf, etc, probably the biggest thing i own currently is my winter deer squishmallow. i don’t own many large plushies (or things in general) as i have limited room for all my things, so i don’t like things that take up too much space (those giant valentine’s day bears would be a nightmare gift for me lol), but i love my squishmallow.
Probably my studio easel! It's convertible, so it can be tilted to make a flat painting surface. For ref:
Regular standing. The tallest part can be extended higher, I usually keep it about 170-ish, it can probably go to +190cm, but it'll become unstable. The bottom bar can be raised too, if working on a small canvas, or standing.
A friend of mine who is almost 30 owns a giant teddybear, and she dresses him up every now and then. She also talks to him when she’s alone. It’s kind of cute, but kind of weird.
The biggest thing I own is probably the tree for my budgies. It ranges from the floor to the ceiling. It’s basically just a long wooden stick with branches and toys screwed into it. The budgies love it, though.
