Need Organization ideas!

I have a ton of donated clothes/coats that I am responsible for storing and organizing. I have a little breezeway type area with a bathroom that connects to the preschool room next door. Inside the bathroom I have a tall sterilite closet type thing that holds underwear (boys in one basket, girls in another), basket for socks, then i have tshirts organized by size (with labeled shelves). In the breezeway I had maintenance install a hanging rod for my coats which I hang by size. Above them in a long shelf that I keep my pants, again by size with a label on the shelf. Under the coats are totes with random things, extra sweatshirts, some shoes, pullups, etc. Then as you enter my office, I have another wardrobe type thing that holds hats/gloves/snowpants and boots. It took me along time and many inservice days to get it all this organized. It was all thrown together in cardboard boxes when I started this job!

My Family Resource Officer keeps them in her office. (Side note-does anyone else call this person a "friskey" -FRYSC- we do and I wonder if thats odd?)

At my previous school I had a large cabinet that I kept a few things in and the FRYSC kept the rest.

I have a closet and I use the copy paper boxes for each size.

I LOVE copy paper boxes! I use them for everything!

I have a book shelf on the wall and copy paper boxes and the clothing sorted into categories like undies, big pants, little pants, big shirts, etc. I generally don't keep big bulky coats.

I have a metal self standing closet. It isn't deep enough for boxes, unfortunately. Since I cover grades 5-12 and we wear uniforms, I have it separated by shelf - gym uniforms on lower shelf; shirts on middle shelf, separated by middle and high school (they wear different shirts); pants on upper shelf, separated into kid, men, and women piles. I have bins on the top for shoes and other odds and ends (socks, belts, ties, etc).

So I asked for a long storage cabinet, and will buy tubs so I can organize stuff around. Hopefully it helps a bit and it will be easier to manage here.
