Short lace succeeds when it looks purposeful
Short curtains can look excellent when the room genuinely needs them. The problem is not the length itself. The problem is using a short curtain in a room that wanted more scale.
Use short lengths where architecture demands it
Windows above sinks, beside banquettes, or in compact utility spaces usually reward shorter lace. The treatment stays out of the way and the room still gets softness and filtered light.
Keep the styling clean
Because short curtains already have a practical feel, it helps to keep the rest of the decision clear. Too much trim or too many extra parts can push them toward clutter.
