I raised my bed with the little feet you can buy at home improvement and organization stores and have plastic bins with lids for some clothes that I wear only about once a month and for some craft supplies. I like the plastic clear bins with lids as the keep dust and our pets from getting into my things.
In the past, I've used the boxes that office copy paper comes in to organize items. They are sturdy, have lids that fit well, and you probably know someone who works in an office who would be happy to bring you a couple of boxes home. Another thing to consider depending on what type of closet you have is how the shelves and bar are arranged.
Sometimes moving the bar a bit lower and adding an extra shelf, or spacing the shelves closer together, can help a lot. Of course, how easy and inexpensive this is to do will depend on how your closet was put together to begin with. One more thing, you can hang a rack on the inside of your door to hold shoes. Even if you don't want to put your shoes in the pockets, you could put hats, gloves, socks, etc in there, freeing up precious drawer and closet space for other items.
Very smart 14 year old. A lot of teenagers could care less about being organized and keeping their room clean. Get yourself one of those over-the-door shoe organizers. Clear is best so you can see everything. Put things under your bed and if you need height those things that raise the bed are inexpensive. Blankets, extra linens, etc can be laid out between the mattress and box springs when you're not using them as in the summer. decorative hooks are really good.
My daughter gave me this tip. I have a couple pretty canvas bags hanging on my wall that I store wallets, etc. but you can store anything in them. I bought one of mine at Goodwill for under $3.00. If space is an issue in your closet those slim hangers are a must. I bought a box of 50 at Bed, Bath, and Beyond for about $20.00.
There are lots of way to store things, and hide the fact that there is storage. One of my favorites is to make a table out of a waste receptacle, put a wooden topper on it and cover with a tablecloth. This makes excellent storage.
You can use plastic storage bags for under the bed. I like lots of baskets, and laundry mesh bags to store things in.
Mirrors brighten a room, even little ones placed along the wall. Those milk crate type of plastic boxes last forever and you can stack them!
