Pot lid storage. Install metal towel bars inside your pantry door. Don't use fancy or bulky bars -- look for simple ones that stand out about 2 inches; mount them only to the rails of solid-core wooden doors. To hang a lid, slide it behind the bar so the knob or handle catches and holds the lid in place.
FAIL... I don't want to drill holes in my cabinet doors to hold up the rod, and command strips just weren't working. Will revisit and keep trying. May try the hook method instead! Genius...the lids to my pots & pans drive me NUTS!
