90 days of weaving raw silk: Hand-pulling threads from silkworm cocoons.

90 days isn't about "looking better than the machine," but about "safety and authenticity."

To put it bluntly: Handmade fabrics cannot be as even, flat, shiny, and precise as machine-made fabrics.Machines make the work better, faster, and more consistent.

But Nam Cao's silk exists according to a different logic: Slow down for safety, slow down for authenticity, slow down to preserve the true nature of the material.And the 90 days begin with a step that the machine cannot properly replace: Hand-spun yarn from silkworm cocoons.

If you need an overall picture of the materials and heritage, see this article: Nam Cao silk /lua-dui-nam-cao.

The difference: hand-spun silk from silkworm cocoons – hand-soaked in cold water.

In Nam Cao's work, there was a period when the craftsman... directly spinning silk from silkworm cocoonsThe craftsman Soak your hands in cold water. To keep your hand "alert," feel the yarn more clearly, and regulate the pulling force.

This action isn't for show. It's for:

• keep the yarn stable, reduces breakage/corrosion when pulled
• Adjust the uniformity by feel and skill., something the machine doesn't have
• reduce frictionAvoid creating fibrous strands in the first place.

Most importantly: this type of hand-spun yarn Not suitable for machine-line weaving. like many industrial fiber lines. The machine can weave fabric evenly and beautifully., But This hand-spun fabric does not meet the proper "yarn properties" standards. (especially when the goal is to preserve the natural, airy, and authentic feel of the raw silk).

Why is 90 days still needed?

90 days is not 90 days of "continuous work". It is the sum of:

• time fiber processing
• time weaving
• time fabric surface after weaving
• time Finishing – Fabric Inspection

And because it's handmade, everything depends on... skill + rhythm + precisionThere is no "speed boost" button, yet the output quality is maintained.

In what ways are handmade crafts "not as beautiful as machine-made"?

To help you communicate effectively and avoid false expectations, here are the facts:

• Not perfectly uniformThe fabric surface has a "lively" feel, with varying thicknesses in different areas.
• Not flashyHandicrafts that lean towards wood and natural materials.
• Not perfect by industry standards.There will be a small margin of error.

But those very things create something that many high-end customers are looking for: honestyAnd when "authenticity" comes along... safety procedures, it becomes a form of value.

"Safety" is the real strength of handicrafts.

If we don't use "uniform beauty" as a standard, then handicrafts have a very clear strength: safe and controllable origin story.

• know where the yarn comes from
• know who did it
• know how the process is maintained.
• know what the fabric inspection standards are.

And for the heritage to endure, that chain must be linked to livelihoods, not just slogans. See also the article: Preserving traditional crafts is inseparable from livelihoods. /conservation-listening.

Humans are the "testing machines" of the manual labor system.

Handcrafted work is not as consistent as machine-made work, so Humans become the quality control system.Examine the fabric surface, feel for stiffness, check for defects, address weak points, and discard any substandard parts.

And this "human" element is often associated with the women in the craft village—those who persistently maintain the rhythm of the craft through each stage. See more: Women and their role in preserving heritage. /women-preserving-heritage.

Conclusion: 90 days is needed to preserve the true essence of silk fabric.

If the goal is Perfectly beautiful, like industrial production.Please choose the machine-sewn fabric.
If the goal is A genuine, natural, safe material with a clear origin.Handmade raw silk is a reasonable choice.

90 days is not meant to be a competition with machines in terms of aesthetics.
90 days is for arrive at a different kind of value.
