How to hang a wool scarf so it actually dries flat
A single hook and a folded scarf can either ruin the shape of the wool or keep it. The difference is in how the fold sits.
Start with the fold, not the hook
Most hooks stretch wool at the exact point of contact, because the whole weight of the scarf pulls on one narrow loop of fibre. Over a season that spot goes thin and shiny while the rest stays full. The fix is to fold the scarf in thirds lengthwise before it goes on the hook, so the fibre bearing the weight is three layers thick instead of one. A scarf that is roughly 70 centimeters wide folds down to about 23 centimeters, which sits comfortably over most wall hooks without hanging past the edges.
Hang it, then rotate it
Once it is on the hook, give the fold a quarter turn every few days. Wool has memory, meaning it holds whatever shape it is left in for long enough, so a scarf that hangs in exactly the same crease all season will keep a visible line even after washing. A quarter turn moves the stress to a new patch of fibre each time, so no single crease becomes permanent. This matters most for scarves carrying lanolin, the natural wax left in sheep’s wool, since lanolin softens slightly in a warm room and makes the fibre more likely to hold a crease under pressure.
Keep it out of direct light
A hook near a window is convenient but not kind to the wool. Sun bleaches the outer layer of fibre unevenly, so a scarf hung the same way for months often ends up paler on the side that faced the glass. Lamplight in the evening does none of this damage, which is one reason a corner lit only by a lamp works better for storage than a bright windowsill, even if the windowsill looks nicer in a photograph.
A note on the wall itself
A plain wall behind the hook is not just a style choice. Wallpaper paste and painted plaster can transfer a faint smell to wool that sits against it for weeks, especially in a small room where air does not move much. A few centimeters of clearance between the folded scarf and the wall, achieved with a hook that projects outward rather than sitting flush, avoids this entirely.
