Timber Venetian blinds
Real timber slats, in stains that show the grain or painted finishes that don't. Warm, substantial, and they read as joinery rather than window hardware — which is why they suit older Queensland homes and anywhere with existing timber.
Often searched as "timber blinds" or "wooden blinds", and worth distinguishing from timber shutters: a Venetian is a blind that raises and lowers on a cord, a shutter is a fixed frame with hinged panels. Venetians cost considerably less. Shutters last longer and add more at resale.
Timber doesn't belong in consistently wet rooms.
