November in Kazbegi's upper valleys is a season of quiet. The summer crowds thin out, the first snow settles on the Greater Caucasus, and woodsmoke rises from mountain villages. It is the perfect moment to picture a ritual familiar to many highland families in Georgia: a large pot over the fire, warm wool, and colours that nature provides without a trace of chemistry.

Georgia has long been known for woollen goods: felt, rugs, knitted socks and woven garments that kept mountain people warm through hard winters. The highlands around Kazbegi (Stepantsminda), with their demanding climate and sheep-herding tradition, are naturally tied to this craft. Flocks graze alpine meadows in summer, and in autumn, when they come down, the season of wool begins: shearing, cleaning, spinning and dyeing.

The most striking shades in this dyeing tradition are warm browns and deep reds. Browns are traditionally drawn from the walnut, from its bark and husks, and walnut trees grow all over Georgia and are familiar to every household. Red comes from madder, a plant whose roots have for centuries been used to colour textiles in the Caucasus and far beyond. To make colour last, dyers use fixatives, and the final shade depends on how long the wool simmers and on the wool itself.

Work at the pot has a special charm in November. Cold air, the smell of smoke and herbs, steam in which skeins slowly darken: an ordinary household task becomes a small performance. Skeins hung over fences to dry against snowy slopes and the silhouette of Gergeti Trinity Church make a picture that is hard to forget. The earthy tones echo the autumn colours of the Dariali Gorge.

Georgian hospitality makes such a journey richer still. In Stepantsminda's guesthouses you will be fed khinkali and khachapuri and warmed with tea, and conversation at the table is the easiest way to learn how families keep home crafts alive. Bring warm clothes, take your time, and always ask before photographing people at work. A pair of woollen socks or a small skein of dyed yarn will carry the warmth of the mountains home with you.
