Direct answer
A material name does not define the yarn blend, count, gauge, structure, density, weight, hand feel, finishing, price or target season. Those variables must be narrowed before a factory can make a meaningful quote or sample plan.
PROCESS CONTEXT
What happened in the washi-yarn discussion
The buyer knew the spring/summer style should use washi yarn, but the percentage, blend, gauge, thickness, feel and target price were not fixed. The factory could compare roughly four to five existing garments rather than pretending the word "washi" described one product.
That comparison opened several smaller questions. The first is why the same material label can lead to visibly different garments. Once the wrong directions are visible, video can be used for first-round rejection.
These images show one available product reference. They do not prove the composition, gauge or result of the other directions discussed in the case.
THE CASE, SPLIT SMALLER
Six decisions instead of one long article
Which garment direction is closest?
Fine and light, heavier and more open, or a different blend and price position.
PreselectWhat can video rule out?
Reject visibly wrong thickness, scale, openness or silhouette before shipping.
ConfirmWhen is the physical reference worth sending?
Ship only when touch, weight, rebound, drape, true color or workmanship remains decisive.
QuoteWhich inputs still need to be fixed?
Define season, feel, weight, composition limits, price, changes, quantity and colors.
AdaptWhat if the target yarn is unavailable?
Mark what a substitute-yarn sample may review and what must stay provisional.
Claim carefullyWhat does the case prove today?
Use it as a requirement-narrowing process, not a completed customer-success story.
