Teen Chok: The Picked Patterns of Northern Thailand's Lanna Weavers
In Mae Chaem and the highland valleys of Chiang Mai, weavers pick warp threads one by one to build the intricate border that defines Lanna's most celebrated textile.
Lanna is a word used loosely now — a marketing designation, a label on restaurant menus in Chiang Mai, a way of saying “northern” without specifying which north. But it was once a kingdom, and the kingdom had a textile tradition so precise that its most celebrated technique is defined not by the whole cloth but by a single strip of it: the border at the hem of a woman’s skirt. Everything that makes the tradition remarkable happens in that strip.
The technique is called teen chok. Teen means foot — or hem, the foot of the cloth. Chok means to pick, or to pull. What the weaver does, thread by thread, is exactly that.
What is teen chok, exactly?
Teen chok is a form of supplementary weft weaving. On a floor loom strung with the main ground weave, the weaver builds additional pattern by picking up selected warp threads with a pointed tool — a stick, a porcupine quill, or simply the fingers — and inserting an extra coloured weft thread through the opening. This supplementary thread does not travel from selvedge to selvedge the way an ordinary weft pick does. It goes only as far as the pattern requires, then turns back. Each row of pattern is built separately, position by position, from marks held entirely in the weaver’s memory.
A single centimetre of teen chok border can involve dozens of individually picked insertions. The technique generates no shortcut. There is no mechanical aid that stands in for the judgment of choosing which thread to raise; the pattern is reconstructed from the weaver’s mental image every time the cloth is made, and no two pieces resolve in quite the same way.
Where does the tradition come from?
The Tai Yuan — the indigenous Lanna people who made Chiang Mai the centre of their kingdom in 1296 — refined teen chok over several centuries at a crossroads of cultures. Lanna was never geographically sealed; trade and diplomacy brought Shan (Tai Yai) weavers from the northwest, Tai Lue communities from what is now Yunnan and Laos, and Mon artisans from the west. Each group contributed vocabulary to the visual grammar of Lanna cloth. The diamond repeats, the stepped pyramids, the stylised forms of the hong bird and the naga serpent that appear in the borders of formal pha sin skirts are the accumulated language of those exchanges, compressed into a strip of cloth sometimes no wider than a hand.
The most celebrated centre of teen chok today is Mae Chaem district, in the western highlands of Chiang Mai province. Mae Chaem sits in a valley at roughly 800 metres, which kept it partly insulated from the market pressures that flattened textile traditions elsewhere. Weavers there maintained the practice through periods when machine-made synthetic cloth made handmade production economically irrational. Many continued because the knowledge was too deep to abandon — because the pattern lived in the hands, and the hands were not ready to stop.
What goes into a teen chok border?
The ground cloth is typically cotton — locally grown, spun, and naturally dyed in the cooler upland climate. For the supplementary weft threads that form the pattern itself, silk is common; for ceremonial pha sin worn to temple on religious occasions, gold or silver thread is inserted alongside the silk, catching light at angles the plain cotton ground cannot. The effect is that the border appears to glow against the darker body of the skirt — an intentional contrast, not an accident of materials.
The pattern vocabulary is geometric but carries specific meaning. The same stepped forms that appear in teen chok borders recur in Lanna temple architecture — in the tiered roof ridges of ubosot halls, in the carved wooden lintels above doorways — suggesting a shared visual logic between the textile and the building. The weavers and the temple carvers were drawing from the same reservoir of form, translating it into different materials for different purposes but never losing the grammar.
How do you recognise genuine teen chok?
A machine-woven border imitation of teen chok will have perfectly identical repeats, crisp edges, and a flat surface. Genuine teen chok carries small, inevitable irregularities — a row that settles slightly differently from its neighbour, a supplementary thread that catches just off-centre. The irregularity is not a flaw; it is the trace of a human decision made at that point in the weaving, the record of where a hand paused to check the memory before it continued.
The supplementary threads also lie at a subtly different height than the ground weave, creating a slight surface relief that is easier to feel than to see. Run a finger along a genuine teen chok border and the pattern is legible with your eyes closed.
How is teen chok used today?
The pha sin — the tube skirt — remains the garment the teen chok border was designed to ornament, and it is still worn in Northern Thailand for temple visits, family ceremonies, and formal occasions. Younger weavers and designers have extended the technique into shawls, cushion panels, and decorative cloth that stands outside any traditional garment context. The vocabulary of the pattern travels without the garment because the pattern carries its own logic; it does not require the pha sin to make sense.
The cotton shawl with Lanna embroidery in our collection draws on this tradition — the picked pattern at the hem a small archive of forms that have moved through the highland valleys of Chiang Mai over several centuries. For a broader account of what to look for when origin matters, the guide to buying Thai handwoven textiles sets out the relevant questions.
The border was always where the work was hardest and the intention most visible. In a tradition where garments were understood partly through their hem — where to know a textile was partly to know its foot — the concentration of labour at the edge was not incidental. It was a declaration. What the weaver picked, thread by thread, was not merely a pattern. It was the statement that the cloth had been made seriously, by a hand that knew what it was doing and had chosen to do it this slowly.
That choice survives in every border that carries it.
