Stage 2 — Construction
Holding a Thread — Both Hands (Basic grip)
What you see in the film
The thread is held between both hands and put under light tension.
What you learn from it
This is the basic grip for every hand check. Under tension the thread shows its true structure.
What you can say to a customer
“You do not need a laboratory. This check takes ten seconds on your own table.”
One Thread on a Plain Background (Visual check)
What you see in the film
A single thread is laid on a plain, high-contrast background and viewed closely.
What you learn from it
Against a plain background you can see twist direction, evenness and loose fibre ends.
What you can say to a customer
“Put the thread on a dark sheet of paper. Whatever we discuss about appearance, we can both see it.”
Holding a Thread — One Hand (Basic grip)
What you see in the film
The same check with one hand, the way it is done directly at the sewing machine.
What you learn from it
The thread runs over the fingers. Tension, smoothness and flexibility can be felt at once.
What you can say to a customer
“This is the grip your operator uses every day. It is the fastest check there is.”
Opening the Twist – Counting the Plies (Twist and plies)
What you see in the film
The twist is opened by hand against its own direction until the single plies separate.
What you learn from it
Now you can count the plies: two-ply, three-ply or a corespun construction with a core inside.
What you can say to a customer
“Two-ply or three-ply is not a detail. It decides strength, seam appearance and price.”
Feel and Flexibility (Feel)
What you see in the film
The thread is moved between both hands: how soft it is, how it bends, how it falls.
What you learn from it
Feel is not a matter of taste. It comes from fibre, construction and finishing.
What you can say to a customer
“You feel the difference immediately. Let me show you where it comes from.”
