Wool, silk and the hand of a carpet

Two carpets can share a cartoon, a palette and a knot count and still be entirely different objects. What separates them is material — where the fleece grew, how it was spun, what carries the warp — and the quality dealers call the hand: how the carpet feels, folds and falls.

Fleece is geography

Highland sheep grow springy, lanolin-rich wool that weaves into carpets with body and gloss; lowland and winter-shorn fleece runs softer and duller. Kork — the fine wool from a lamb's first shearing, taken at the shoulder and flank — gives the silk-like pile of the best Isfahan and Kashan work. When a carpet's surface seems to hold light rather than reflect it, kork is usually the reason.

The spin and the ply

Hand-spun yarn is never perfectly regular, and that irregularity is visible in the pile as a faint, living variation no machine spin reproduces. Tightly plied yarn knots into a crisp, articulate surface; softer spinning gives depth and blur. Neither is superior — a gabbeh wants the one, a Nain the other — but each must match the design's intent.

What the hand tells you

Fold a corner. A wool-foundation tribal piece folds like cloth; a cotton-foundation city carpet resists gently and returns flat; a wet-loom Bidjar barely folds at all. Each behaviour is correct for its type, and each is nearly impossible to counterfeit. It is why serious buyers still insist on touching a carpet before acquiring it — and why we arrange private viewings rather than asking a photograph to do all the convincing.
