Congrats on heading off to college, how exciting!!
I think the key to storage in a dorm room, as in any room, is considering storage for all surfaces and spaces! While boxes that can fit under your beds and desks are important (just like cute folders and organizers for your desk drawers), so is vertical storage!
Think of how you can use your walls not just for decor, but to hold some key items! These DIY Wall Pockets are great because they combine both storage and style. Also command hooks can hang things on the inside walls of closets, which is a great place to store things because no one sees it!
