I've got a small/awkward room and way too much stuff (mostly clothing). So I've had to get creative in where I store things and maybe I'll give you some ideas for dorm room or bedroom storage.
A massive antique trunk. This probably won't work in a dorm, but in a bedroom, this thing is amazing. It holds so much stuff it's ridiculous. I store things that I usually don't need in there because I've got those bags (and usually some other things too) stacked on it. I got this one at a garage sale a few years ago. I'm not sure where the smaller luggage and bag are from.
Under-the-bed storage. I've got three rolling bins under my bed, similar to these. One's full of clothes, one's full of shoes, and the other has books and miscellaneous things in it. They're really useful. I've also got two more plastic bins under the bed for more storage.
Shelves. I've got three long shelves above my computer. The highest one has decorations on it. The middle one has decorations, scarves, and clutches on it. That way I can reach the scarves and clutches and they double as a decoration. And the lowest one has my stationary, some beauty products, nail polish, and various desk things on it. I've tried to make everything double as decoration.
Wall storage. I've put six sunhats on the wall so they're not taking up space anywhere else. They definitely double as decor.
So for the most part, I've tried to make the things I wear double as decor. It's worked well and it's fairly functional. I've even DIY-ed a necklace display. You can see that post here.
Do you have any bedroom storage ideas?
