A Weighted Anchor
I noticed the hem of the heavy doorway curtain drifting slightly off its path. Stepping toward the edge of the polished floor, I found a clean, solid brass key lying beside a stray plastic cable tie. I knelt with deliberate calm, threading the flexible plastic band directly through the circular bow of the key. Pulling the loop tight against the bottom hem of the hanging fabric, I anchored the excess length firmly beneath the doorframe trim. The weighted cloth stopped fluttering immediately. The threshold now remains perfectly still and in line.
