Jar Lid Magnet Board: The Backing That Holds
The magnet strength behind each lid decides whether your board holds a week of notes or drops everything by Wednesday.

Metal jar lids are free, sturdy, and already sitting in your recycling, but they only hold things on a wall if the magnet behind them is strong enough to pull through the lid's thickness. Skip that check and a lid full of paper clips will slide down the board and spill. Flat ceramic magnets glued with a thin bead of adhesive give you the grip you need, and we'll set up the board so it stays tidy for good.
What You'll Need
- Metal jar lids, 6 to 8 assorted sizes, free from your recycling
- Baking sheet or thin metal tray, about $3 at a dollar store, used as the mounting board
- Strong disc magnets, 1 inch ceramic, about $6 for a pack
- Clear-drying strong adhesive, such as E6000, about $4
- Spray paint, optional, a leftover can in a bold color
- Small glass jars, 6 to 8 with matching lids, for spices or clips
How to Build It
- Wash the jars and lids in hot soapy water, then dry them completely so the adhesive bonds to bare metal.
- Sand the top of each lid lightly with fine sandpaper or a scrub pad if it has a slick coating, then wipe off the dust.
- Paint the lids with thin even coats of spray paint outdoors or in a ventilated space, then let them dry for an hour. Skip this if you like the metal look.
- Glue one magnet to the underside of each jar's bottom, not the lid, with a pea-sized dot of adhesive, then press firmly for 30 seconds. The jars then stick to the metal tray, and the lids can unscrew freely.
- Cure the glued jars for a full 24 hours, upright and untouched, so the bond reaches full strength before any weight goes on.
- Mount the metal tray to the wall using two heavy-duty screws into studs, or drywall anchors rated for 20 pounds if there is no stud.
- Test one jar at a time by filling it and pressing it to the tray. If it slides, add a second magnet beside the first, then fill the rest.
Group jars by color or lid size and leave an inch of tray between them so the board reads as a deliberate display, not clutter. Keep the heaviest jars along the bottom edge, where the tray is best supported, and put light items like paper clips up top.
