Before silk ever reached the loom in Bhutan, it had already travelled.
It crossed forests, river valleys, mountain ridges and narrow passes where journeys were slow, uncertain and often dangerous. Traders moved with pack animals and carefully bundled goods through routes shaped as much by weather and geography as by politics. Yet somehow, fine silk, dyes and precious materials from the plains of Assam and neighboring Himalayan regions found their way into remote Bhutanese valleys.
How these delicate fabrics travelled across such difficult terrain is part of what makes Bhutan’s textile history so fascinating.
In Bhutan, a piece of fabric is rarely just a piece of fabric. Long before it becomes a traditional garment, ceremonial scarf, monastic shawl or household textile, it already carries a story.
Bhutan’s textiles reflect centuries of craftsmanship, cultural exchange, religious values and social tradition. Among the many materials used by Bhutanese weavers, two varieties of silk have played particularly important roles: Mulberry Silk and Eri Silk.
Mulberry Silk is admired for its refined appearance, softness and subtle elegance. Eri Silk, often called peace silk, is valued for its warmth, durability and more compassionate method of production. Although each silk has a distinct identity, together they reveal how Bhutanese textile traditions evolved through an exchange of materials, ideas and beliefs across the Himalayan region.
Silk Across the Himalayan Trade Routes
Bhutan’s silk tradition cannot be understood without looking beyond its borders.
Historical inventories from the seventeenth century refer to cloth being exchanged as gifts with Tibet and Assam, while domestically produced textiles were also collected as taxes. Such records suggest that Bhutanese weaving traditions were never completely isolated. Instead, they developed through centuries of interaction with neighboring communities.
Much of this exchange moved through the Duars, the network of southern gateways and passes connecting Bhutan’s mountain valleys with the plains of Assam and the wider Trans-Himalayan trading world.
These were not easy commercial routes. Traders had to negotiate steep terrain, dense forests, rivers, changing weather and long distances. Goods were carried in relatively small quantities, making fine textiles, silk yarns, dyes and other valuable materials particularly suitable for this kind of trade.
Through seasonal barter and regional exchange, Bhutanese communities gained access to high-quality silk and other materials that gradually became woven into the country’s own textile vocabulary.
But the movement of silk was not purely economic.
Materials were selected, interpreted and transformed within a society deeply influenced by Vajrayana Buddhism. Ideas of compassion, peace and respect for living beings shaped cultural preferences as much as beauty or practicality did. This is particularly significant in understanding the later importance of Eri Silk, whose method of production allowed the silkworm to emerge from its cocoon before the fiber was processed.
In this way, a thread arriving through a distant mountain pass could become something distinctly Bhutanese: not merely imported material, but part of a living tradition shaped by landscape, faith and generations of skilled hands.
Mulberry Silk: Precision, Ceremony, and Quiet Luxury
Mulberry Silk became closely associated with Bhutan’s aristocratic and upper classes because of its smooth texture, fine fibres, and luminous appearance.
Its yarn is exceptionally uniform, allowing experienced weavers to create highly detailed geometric designs with remarkable precision. This quality made Mulberry Silk especially suitable for some of Bhutan’s most intricate and prestigious textiles.
One of the best-known examples is the Kishuthara, an elaborate form of kira traditionally worn by aristocratic, elite, and upper-class women. Its brocade-like patterns require extraordinary skill and patience. A single Kishuthara can take a master weaver many months—and sometimes nearly a year—to complete.
The distinctive sheen of Mulberry Silk also makes it an important material for formal and ceremonial occasions. It may be worn during Tsechus, one of Bhutan’s most celebrated festivals held according to the tenth day of lunar calendar, as well as during royal ceremonies and important government events.
In these settings, Mulberry Silk communicates elegance without appearing excessive. Its beauty lies in the precision of the weave, the richness of the pattern, and the quiet confidence of the finished garment.
Eri Silk: Warmth, Compassion, and Spiritual Meaning
While Mulberry Silk is often connected with ceremony and refinement, Eri Silk represents another important dimension of Bhutanese life.
Eri is commonly known as peace silk because the silkworm can emerge naturally from its cocoon before the fibres are processed. This method makes the material especially meaningful within Buddhist communities, where the preservation of living beings is an important spiritual principle.
The silk is particularly suitable for Bhutan’s colder climate. It is soft, insulating, durable, and able to provide warmth during long periods of stillness. For this reason, it has traditionally been used in garments and shawls worn by monks, or Gelongs.
Monastic shawls, including those associated with religious practice, can be woven using Eri Silk yarn. The material helps keep monks warm during extended meditation, especially in high-altitude monasteries where temperatures can fall considerably.
Its importance goes beyond clothing. Because of its connection to Buddhist values, Eri Silk may also be used for lining spiritual altars and wrapping sacred texts.
The material has also found a place within royal life. During colder public appearances, members of Bhutan’s royal family may wear Eri Silk shawls that combine warmth, comfort, and understated elegance.
Two Silks, One Cultural Story
Mulberry Silk and Eri Silk are often viewed through different lenses.
One is admired for its fine texture, luminous surface, and association with celebration and social prestige. The other is respected for its warmth, durability, and connection to compassion and non-violence.
Yet they are not competing traditions.
Instead, they complement one another. Mulberry Silk represents the ceremonial, festive, and highly decorative side of Bhutanese culture. Eri Silk reflects its peaceful, spiritual, and responsible character.
Together, they reveal a deeper understanding of luxury—one that is not defined only by rarity or appearance, but also by craftsmanship, meaning, responsibility, and cultural continuity.
Every thread becomes part of a larger narrative. It connects Bhutan’s present-day weavers with historic trade routes, religious principles, royal traditions, and generations of knowledge passed from one artisan to another.
In Bhutanese textiles, beauty and responsibility are woven together. Mulberry and Eri Silk remind us that progress does not have to mean leaving tradition behind. Sometimes, moving forward means carrying the most valuable parts of the past with us.
