Prefer to make your own inserts? You have plenty of options. Clip together sturdy little cardboard jewelry boxes to create neat storage for pens and pencils, lipsticks, plastic flatware—whatever is cluttering your drawer. Slice off the tops and the bottoms of cereal boxes and fill them with loose odds and ends. Or try shoe boxes: Cut them in half, along the length or width, and fill the resulting compartments with folded briefs, socks, or stacked bras.
