The Sampling Process Explained: From Tech Pack to Approved Swatch

By the Charisma Fashion India team · Mumbai · October 30, 2026

Our Mumbai atelier has run this process for design houses since 2000. Sampling is not a formality before the real work; it is where technique, cost, and feasibility are settled. This guide walks through each stage as our team actually handles it, and what a designer can do at each step to get a closer first result.

1. The tech pack: what we need to start

A useful tech pack gives our team artwork at actual size, not just a mood image. It shows where the embroidery sits on the garment, the ground fabric it will be worked on, colour references, and the intended technique or a reference swatch that captures the desired effect. Dimensions matter: a motif drawn at one scale and embroidered at another changes density, weight, and cost. If a house does not yet have a full tech pack, a clear artwork file, a placement sketch, and a fabric sample or description are enough for our team to advise what else is needed before work begins.

2. Interpretation: turning artwork into stitches

Artwork on paper is not yet embroidery. In the interpretation stage, our team decides how each element will be built — tambour or aari for fine lines, zardozi for raised metallic work, bead and sequin setting for surface sparkle, thread work for softer areas. Fine painted detail may need to be simplified so it reads clearly in thread; very dense areas may need a lighter build so a finished garment still drapes. Our team flags these choices early, because a decision made on the swatch frame is far cheaper than a correction made in production.

3. Materials: sourcing and substitution

Next, materials are gathered to match the brief: threads, beads, sequins, stones, and wires in the specified colours and finishes. Sometimes an exact material is unavailable or behaves differently at the required scale — a bead may be too heavy for a sheer ground, for example. When that happens, our team proposes the closest substitute and shows it on the swatch itself, rather than deciding silently. A designer should always judge a substitute in the hand, under real light, not from a photograph alone.

4. The first swatch: what to look for

The first swatch is a working draft in fabric, not a final verdict. Judge it on four things: scale and proportion of the motif, stitch density and coverage, colour against the brief, and hand-feel — weight, flexibility, and how the reverse side sits against skin or lining. Turn it over. A clean reverse, with no loose ends or bulky knots in the wrong places, tells a designer a great deal about how production pieces will finish. For background on reading hand work itself, see our guide to hand embroidery vs. machine embroidery.

5. Corrections: one consolidated round at a time

Corrections work best when they are specific and gathered into a single note per round: make this motif smaller, open up this area, deepen this colour, replace this bead. Marking changes directly on photographs of the swatch, or on the physical swatch itself before returning it, removes ambiguity. Scattered comments across many emails are where sampling most often goes wrong. One to two focused rounds are normal; if a design needs a fundamental change of technique, our team will say so plainly and re-quote that stage rather than patching a build that will not hold in production.

6. Approval: the swatch becomes the master

Once a designer approves a swatch, it stops being a sample and becomes the master standard for the order. It stays with the production file, and finished panels are compared against it for density, colour, and placement before checking, finishing, and packing. Pricing and lead time for production are confirmed against that approved build — not against the original artwork — because the approved swatch is what will actually be made. Keep a duplicate or detailed photographs on the buying side as well, so both sides are checking against the same reference.

Frequently asked questions

What should a tech pack for embroidery sampling include?
Artwork at actual size, placement, technique and material references, colour references, ground fabric, motif dimensions, and any areas that must stay free of embellishment.

How long does a first embroidery sample swatch take?
Typically one to three weeks depending on density, technique, and materials, plus shipping. Our team confirms a stage-by-stage timeline before sampling begins.

How many correction rounds are normal in embroidery sampling?
One to two focused rounds. Corrections are clearest when marked on photos or on the physical swatch and sent as one consolidated note.

What happens after a swatch is approved?
The approved swatch becomes the master standard. Every production panel is checked against it before finishing and shipping.
