Use mismatched forks to hold business cards, receipts, and other notes. Hang them on self-adhesive hook-and-loop fastener dots.
A vintage muffin tin keeps small items separated and contained in a desk drawer. For deeper storage, try a popover pan.
A food dome and platter make bill-paying an occasion. Store your checkbook and calculator under the dome. Drawer pulls make clever hooks for reading glasses and keys. Use curtain clip rings to hold papers.
Keep everything from pens and cards to paper clips and tacks in pretty teacups or demitasses. Elsewhere, use small bowls, tumblers, or bright mugs to hold thumb tacks, paper clips, pens. A picture ledge mounted on the wall keeps them in reach but off the desk.
