Understanding Indian Textiles Through the Pre-Loom, On-Loom and Post-Loom Taxonomy
Indian textiles are often introduced to us through names: Banarasi, Kanchipuram, Patola, Paithani, Ajrakh, Kalamkari, Bandhani, Chikankari, Jamdani, Pochampally, Sambalpuri, and many more. These names are beautiful and culturally rich, but for a learner they can also become confusing.
Some names refer to places. Some refer to techniques. Some refer to communities. Some refer to products. Some refer to materials. Some refer to motifs or market identities. A sari may be known by its town, by its weave, by its border, by its community association, or by the way it is decorated.
So, how does one begin to understand the vast and complex world of Indian textiles?
One very useful answer comes from the report Mapping Indian Textiles by Ruchira Ghose, prepared under the Tagore National Fellowship and supported by the Indira Gandhi National Centre for the Arts, New Delhi. The report proposes a powerful way of classifying Indian handmade textiles: not merely by region or product name, but by asking a more fundamental technical question:
At what stage does the design enter the textile?
This question leads to a clear and elegant taxonomy:

Pre-Loom, On-Loom, and Post-Loom.
The Central Idea: Where Does Design Enter?
The report’s classification is based on what it calls the location of design in the handmade textile process. In simple words, this means identifying the stage at which the pattern, motif, colour arrangement, or ornamentation becomes part of the textile.
The design may enter:
| Stage | Category | Meaning |
|---|---|---|
| Before weaving | Pre-Loom | Design is prepared on the yarn before it reaches the loom |
| During weaving | On-Loom | Design is created while the fabric is being woven |
| After weaving | Post-Loom | Design is added after the cloth has already been woven |
This taxonomy does not replace regional names. It does not make words like Banarasi, Kanchipuram, Ajrakh, Patola, or Kalamkari unnecessary. Instead, it gives us a deeper technical structure underneath those names.
It helps us move from simply asking:
“Where is this textile from?”
to also asking:
“How does this textile become designed?”
That shift is extremely important.
1. Pre-Loom: Design Before the Loom
In Pre-Loom textiles, the design is created before the yarn is placed on the loom. The most important example of this category is Ikat.
In Ikat, the pattern is not drawn directly on cloth. Instead, the yarn itself is tied and dyed according to a planned design. The tied portions resist the dye, while the exposed portions absorb it. After dyeing, the yarns are arranged on the loom and woven. Only then does the final design emerge.
This is why Ikat often has a soft, slightly blurred edge. The design exists in the yarn before weaving, but it becomes visible as a complete pattern only when the warp and weft come together.
A beautiful way to understand Pre-Loom design is this:
In Pre-Loom textiles, the design is hidden inside the yarn and revealed through weaving.
The report identifies different types of Ikat:
| Type of Ikat | What happens |
|---|---|
| Warp Ikat | The warp yarns carry the design |
| Weft Ikat | The weft yarns carry the design |
| Double Ikat | Both warp and weft yarns carry the design |
| Combined Ikat | Warp and weft ikat appear in the same textile, though they may not overlap fully |
Indian examples include Odisha Bandha, Sambalpuri Ikat, Pochampally Ikat, Telia Rumal, and Patan Patola.
Pre-Loom textiles require remarkable planning. The artisan must imagine the final design before the cloth exists. The design must be translated into yarn sections, tied, dyed, aligned, and woven. In Double Ikat, where both warp and weft must meet precisely, the level of calculation and skill becomes extraordinary.
So, Pre-Loom textiles are not merely woven. They are pre-imagined, calculated, dyed, and then woven into visibility.
2. On-Loom: Design During Weaving
In On-Loom textiles, the design enters during the weaving process itself. Here, the loom is not only a tool for making cloth; it is also the place where pattern is created.
This category includes both simple and complex forms of design.
Simple On-Loom Patterning
Some On-Loom designs are created by changing the colour, thickness, spacing, or arrangement of yarns.
For example:
| Design Type | How it is created |
|---|---|
| Stripes | Variation in warp or weft yarns |
| Checks | Variation in both warp and weft |
| Shot fabrics | Different colours in warp and weft create changing tones |
| Texture effects | Variation in yarn thickness or spacing |
This is important because it reminds us that design does not always mean elaborate motifs. A stripe, a check, a colour shift, or a textural rhythm can also be a design decision built directly into the weaving process.
Brocade and Jamdani
More complex On-Loom textiles include brocade and Jamdani.
In brocade, the pattern is created on the loom using extra or supplementary yarns. These extra yarns may be supplementary weft, supplementary warp, or both. They are not necessarily required to create the basic structure of the fabric, but they create the decorative motif.
Jamdani is a particularly delicate form of this logic. In Jamdani, a fine ground fabric is woven with regular warp and weft, and then supplementary weft threads are inserted by hand to create motifs. These motifs often appear to float on the surface of the fabric.
A simple way to understand Jamdani is:
Jamdani is woven ornament. The ground cloth is formed by the regular warp and weft, while the motif is added during weaving through supplementary weft.
Examples include Dhakai Jamdani, Tangail Jamdani, and Uppada Jamdani.
Tapestry
Tapestry is also an On-Loom technique, but its logic is different from Jamdani.
In tapestry, the design is not added as an extra motif over a ground fabric. Instead, the coloured weft yarns that create the design are part of the actual structure of the cloth. The pattern and the fabric are built together.
This distinction is important.
In Jamdani, the motif is supplementary.
In tapestry, the motif is structural.
Examples of Indian textiles using tapestry-like techniques include the Kani shawl of Kashmir, the Paithani sari of Maharashtra, and the Dhurrie.
A useful line of distinction is:
In Jamdani, the motif is introduced into the fabric. In tapestry, the motif becomes the fabric.
Or even more simply:
| Feature | Jamdani | Tapestry |
|---|---|---|
| Design yarn | Supplementary weft | Structural or complementary weft |
| Base fabric | Exists independently | Built along with the design |
| Visual effect | Motifs appear to float | Pattern is integrated into the cloth |
| Textile logic | Ornament added during weaving | Fabric constructed through pattern |
This comparison shows the strength of the taxonomy. It helps us see that two textiles may both be “woven designs,” but the role of the design yarn may be very different.
3. Post-Loom: Design After the Cloth Is Woven
In Post-Loom textiles, the cloth is woven first. The design is added later.
This category includes a very wide range of Indian handcrafted textile traditions. Here, the loom may create the base fabric, but the final identity of the textile emerges through painting, printing, dyeing, embroidery, appliqué, or other surface techniques.
The report identifies broad Post-Loom groups such as:
| Technique Group | Examples |
|---|---|
| Painting | Kalamkari, Mata ni Pachedi, Rogan |
| Printing | Ajrakh, Bagh, Bagru, Sanganer |
| Resist dyeing | Bandhani, Leheriya, Dabu |
| Embroidery | Chikankari, Kantha, Phulkari, Kasuti |
| Appliqué | Pipli appliqué and other appliqué traditions |
In Post-Loom textiles, the cloth becomes a surface for further work. The design may be drawn with a pen, stamped with a block, resisted with wax or mud, dyed in stages, embroidered with thread, or built up by attaching another fabric.
This category is especially rich because it brings together textile skill, chemistry, drawing, hand control, ritual practice, community identity, and surface ornamentation.
For example, Kalamkari involves drawing and dyeing with mordants and natural colours. Ajrakh combines block printing with resist dyeing. Bagru uses hand block printing, often with natural dyes and Dabu resist. Rogan uses an oil-based paste applied by hand to create raised patterns. Mata ni Pachedi combines painting, printing, ritual narrative, and goddess imagery.
A useful way to remember Post-Loom textiles is:
Post-Loom textiles remind us that weaving is not always the end of textile creation. In many Indian traditions, weaving is only the beginning.
Why This Taxonomy Is So Useful
The Pre-Loom, On-Loom, and Post-Loom framework is powerful because it gives us a way to organize a very complicated field.
1. It reduces confusion
Instead of trying to memorise hundreds of names, we can begin with one question:
When does the design enter the textile?
If the design is prepared on the yarn before weaving, we are in the world of Pre-Loom. If the design is created during weaving, we are in the world of On-Loom. If the design is added after the cloth is woven, we are in the world of Post-Loom.
This does not solve every classification problem, but it gives us a clear starting point.
2. It separates product from process
A sari is a product form. But the technique used to create it may be Ikat, brocade, Jamdani, tapestry, printing, painting, embroidery, or appliqué.
So the word “sari” tells us what the object is.
The taxonomy tells us how the design was made.
That difference is very important for students, museum professionals, researchers, designers, and serious textile enthusiasts.
3. It helps museum documentation
The report was written in the context of public museums and textile collections. Museums need to classify, label, store, display, and explain textiles accurately. A taxonomy based on the location of design can help create better accession registers, gallery labels, digital archives, and educational displays.
Instead of simply saying “silk sari” or “printed cloth,” a museum can describe the material, technique, process, region, use, maker community, and design logic more precisely.
4. It reveals hidden skill
Once we know when design enters the textile, we begin to appreciate the invisible labour behind the object.
We begin to see:
the mathematical planning of Ikat,
the delicate insertion of supplementary weft in Jamdani,
the structural intelligence of tapestry,
the chemistry of mordants and resists in printing and dyeing,
the drawing skill of Kalamkari,
the patience of embroidery,
and the compositional intelligence of appliqué.
The taxonomy helps us look beyond surface beauty into process intelligence.
Where the Taxonomy Becomes Complicated
Indian textiles are rarely simple. Many traditions combine techniques. This is where the taxonomy must be used carefully.
For example, a textile may be woven with one technique and then dyed, painted, printed, or embroidered later. Some Odisha saris combine Ikat with extra-weft patterning. Ajrakh combines block printing and resist dyeing. Mata ni Pachedi may combine painting and block printing. Kodalikaruppur saris historically involved weaving, metallic thread, resist work, and painting or printing.
So the taxonomy should not be treated as a rigid cage. It is better understood as a map.
A map helps us enter the landscape, but it does not replace the richness of the landscape itself.
The most mature way to use this framework is to ask:
What is the primary location of design?
Are there secondary design interventions?
Does the textile combine more than one process?
This approach respects both structure and complexity.
From Names to Processes
The greatest value of this taxonomy is that it changes the way we see Indian textiles.
Instead of seeing Indian textiles only as a list of regional names, we begin to see them as systems of making.
Patola is not just a famous sari; it is a Pre-Loom Double Ikat marvel.
Jamdani is not just a delicate fabric; it is a supplementary-weft On-Loom ornamentation technique.
Paithani is not just a Maharashtrian sari; it involves a tapestry logic where design and structure are deeply connected.
Kalamkari is not just painted cloth; it is a Post-Loom tradition involving drawing, mordants, dyes, washing, and repeated hand processes.
Ajrakh is not just a printed textile; it is a sophisticated sequence of resist, mordant, dye, block, and repetition.
This is the deeper gift of the Pre-Loom, On-Loom, and Post-Loom taxonomy.
It allows us to move from names to processes, from surface to structure, and from decoration to design intelligence.
To understand Indian textiles deeply, we must ask not only where they come from, but how their design comes into being.
And for that, the taxonomy introduced in Mapping Indian Textiles gives us a simple, elegant, and powerful beginning.
