I don't know that I have any amazing, original advice, but here are the things that I'm trying with my kids.
First, I label where things go in each dresser drawer. It's actually mostly for me, because I can't remember where everything goes in every single room of the house! But as mine starts reading, he knows that pajamas go on the right, underwear on the left.
Second, he has a tall oval garbage can for a dirty laundry hamper. I like it in his closet so it doesn't make the room look so cluttered. But it's easy for him to pick up his dirty clothes and dump them right there in his room.
Third, bookshelves. We moved and I haven't had bookshelves in my kids rooms for almost 2 years, and it's driving me nuts! They help keep toys, books and knicknacks organized and displayed attractively. We have a short one in one of my boys' rooms. It's not nearly enough. I want a full-sized tall one for each boy.
Fourth, is bins. I found adorable square plastic bins in two sizes at the dollar store. The colors are limited, but they fit perfectly on a bookshelf. They're great for containing groups of smaller objects, like small dinosaurs, hot wheels, flash cards, (or maybe purses, jewelry, crayons, etc) and because you can't see what's inside, they look much neater/cleaner. You should probably label those, too.
Fifth, clean clothes tubs. I bought large Sterilite dishpans at Walmart for about $2.50 each. Then I printed each family member's name large on plain paper and taped them with clear packing tape onto the front of the tub. When I fold laundry, I sort it into each person's tub. Then the person is responsible for taking their tub of clean clothes and putting everything away. I also have a tub labeled "kitchen" and "socks" because it just works better that way.
For labeling, I bought clear print-on return address labels. They actually have some at my local dollar store, so they can be really cheap, but I bought mine at Walmart for about $8. You only really have to print one row at a time if you're careful with removing the labels (so as not to munch up the rest of the sheet, so it stays smooth and will go through the printer again). I also label the shelves in my pantry and kitchen, so it's not too hard to find enough things to print. If I DO need to fill up a sheet fast, I print them as actual return address labels! You will always use those up.
I hope some of my ideas will fit into your life!
