Alpaca
“Lightweight, warm, and smoother than many wools”
Alpaca can feel sleek and warm without much weight. Its fuzziness and tendency to shed depend on fiber length, yarn, and blend.
Like a lightweight, soft winter throw
The surface is likely to catch the light softly, creating a gentle sheen.
A fine nap may give the surface a softly brushed look. How visible it is depends on fiber fineness, yarn construction, and finishing.
It may drape softly while keeping some loft.
