I came across this great tip for designating items for donation in the January 2007 issue of Martha Stewart Living Magazine. Martha's suggestion was to hang an extra-large tote bag in a closet or near the back door so that whenever you came across an item that you wanted to give away, you could simply put it in the tote bag. When the tote bag is full, you can arrange to drop it off at your favorite non-profit thrift shop.
