I keep a "future bin" in each of my three boys' closets for hand-me-downs and clothing I purchased on clearance in larger sizes. I purge their closets about once a season, when they are at school or napping. Anything I remove goes to one of three places: the younger brother's future bin; the charity bin, which is in my closet; or the trash.

Many charities, such as Goodwill, call quarterly to let us know they will have a truck in the area, so I don't have to load my car and make an extra trip. When they call, I leave the bin out front for pickup, and they hang the receipt (for tax purposes) on my doorknob. This is also a good time to get rid of any toys that the kids have outgrown.
