I am a big sale shopper so when I see our normal things on clearance, I will buy several at a time so I store them in our linen closet.
We have 2 linen closets. The one by the kids room is smaller and has all their towels on one shelf, sheets on the other. The top shelf has the humidifier and then the middle shelf has extra shampoos and conditioner's.
Our linen closet is large and is in our master bath. I organized it last year and it looks GREAT! I downsized all our towels to about 6-8 and they are rolled and put in 2 big round containers from the dollar store on one of the shelves.
Then I have other white containers that are a little bigger and wider than a shoe box. I think I have about 6, 3 on each shelf. They hold hair products, sun products, tooth products, medical, deodorants and one for misc like razors. I also have a big basket that holds all the extra pads for the girls in the house. On the floor is a big collapsible hamper that we put all the TP in so when the kids need some, they just grab them from there.
Oh and on the other shelf I have 2 bigger baskets that have rolled hand towels and the other has extra pillowcases.
It looks great and I've been able to keep it up and everyone knows exactly where the stuff is when they run out. It's easy for me to see if we need more of something or have enough. Good luck on getting organized!
