Crimson and Indigo Sarouk Floral, Hand-Knotted Wool Rug

100% wool pile, hand-knotted to the 16/16 quality, with a natural fringe at both ends. A square knot count — the same number of knots per inch in both directions — is what allows curved drawing to read evenly, and it is the reason the fine detail here holds together at this small size.

A crimson ground is among the more forgiving colours a rug can have, and the indigo border better still. The cream and gold in the flowers are the vulnerable colours — they are the palest things here and the first to grey, and at this level of detail a loss of contrast costs more than it would on a coarser rug.

The tag on this rug gives its quality as 16/16 — sixteen knots to the inch in each direction, so the knots are square rather than stretched. That matters for a curvilinear design like this one. A knot grid cannot draw a curve; it can only approximate one in steps, and when the grid is denser vertically than horizontally, curves come out lopsided — a stem bending left looks different from the same stem bending right. On a square count, both directions step at the same rate and a curve reads the same whichever way it turns.

Look at the arching stems and you can see the benefit. Each one tapers as it curves, thinning from its base towards its tip, which takes several knots of graduation to achieve and would simply be lost at a coarser count. The blossoms carry three or four colours each within a few millimetres. Fold the rug down its length and the two halves answer each other stem for stem, and because the count is square, the mirrored pairs curve identically rather than one looking tighter than the other. It is the sort of quality that does not announce itself from across a room but is unmistakable when you crouch down.
