One of my favorite "tricks of the trade" is to use open storage bins whenever possible. It's amazing how a lid can deter the average person from putting an item back where it belongs. Baskets and bins are inexpensive and easy to find. They act as a drawer that you can pull out as needed. And the best part? What goes inside the bin doesn't necessarily have to remain neat and tidy, so long as you only toss in items that belong.
The canvas bins in the pictures above were purchased at Lowe's, but you can find similar styles at Target, Bed Bath & Beyond, the Container Store, etc. I like the uniformity in size and color, and the fact that they can be labeled clearly on the front. Bins like these can be given different "real estate" in your closet for different seasons. For example, you may rotate your Scarf bin to a top shelf and swap it out for the Bathing Suit bin as the seasons change from winter to summer.
