sounds like my house. We also have 1000 sq ft house with family of 5. kids ages 18, 15, and 11. Small closets and no place to put things. Toys are in storage drawer/bins. they hold a lot and more organized than toy boxes. We have one of those shelf units over the toilet. It has 3 shelves and holds tons of towels. half our basement has shelves wall-to-wall and store a lot on those shelves. All the beds have organizers underneath. I have one under my bead for all my sweatshirts and slide it out to the side when I need a shirt. I don't put the lid on it so I can slide it easier and don't have to take it completely out to get the lid off. I also store my dress shoes under the bed at the foot of the bed. It is easier to find them than to sort through a big pile in the closet floor.
In the boys closet we put another rod in it.. halfway between the top one and the floor. Oldest son's clothes are on top rack and youngest son on bottom rack. It worked well when they were smaller but now the top clothes are hanging over the bottom ones and sometimes shirt tails get stuck under hangers but it works. Otherwise we wouldn't fit both boys clothes in one closet without the 2 poles.
have few kitchen cabinets. so use a drawer organizer. I have one drawer for utensils that mainly gets used for cooking--big spoons, spatula's, etc.
2nd drawer is for baking utensils--measuring cups/spoons, cookie cutters, and anything else you use for baking. 3rd drawer has mixer, and several misc items. I have a shelf in the basement for all the kitchen appliances like crockpot, deep fryer, blender, and other appliances that don't get used everyday. I have a med size bin in the floor of the pantry that holds all the lids.
We use one of the big little tyke type plastic toy boxes to store blankets. You can cram a lot of blankets into those big toy boxes and doesn't take up your closet space and they are bulky and don't stay on shelves very well.
we use an old dresser that is also in the basement to store movies in. They are easy to find and each drawer holds a lot of DVD's.
roll your t-shirts and jeans.. you can fit a lot more in the drawers when they are rolled.
can store camera tri-pods and other narrow things behind the couch. No one will see it and can utilize a little space behind your couch if it is against a wall. That won't work well if your couch is in the middle of the room like open space rooms.
I store meds above the refrigerator in baskets. Little kids can't reach them and the basket hides where no one knows what's in it.
Go through your closets.. If things haven't been worn for a year then get rid of it. If you haven't worn it in a year, you probably won't ever wear it again.
My husband and I share a 6 foot closet. He has half and I have half.
work at putting things away right after you are done using it. It helps to keep everything in it's place and organized if everyone would put things away as they use them.
Good luck getting orgainized.. It is a challenge with a small house.
