Polyester wadding and fills: spray-bonded, silk-like and pearl
Spray-bonded polyester wadding, silk-like siliconised hollow fibre and bead fills — how apparel loft is built when it is not down.

Press snaps versus sew-on buttons
Four-part snap fasteners (socket, stud, prongs) compared with sew-through and shank buttons — when to rivet, when to sew.

Jeans buttons and rivets
Tack buttons versus pocket rivets — ligne sizes, hollow versus resin-core caps, and why the die is half the product.

Matching lining to shell: shrinkage, static and care
Keep lining shrinkage within a couple of percent of the shell, lighter in mass, no darker in shade — and why viscose lining in a washable wool is a hem that kicks.

How a press snap is built
Cap, socket, stud and prong — S-spring versus ring spring, size codes, and why the punch is part of the product.

Lining construction and specs: T, denier, gsm, slip and tear
190T and 210T polyester taffeta, yarn denier, mass, down-proof finishes — the numbers on a lining mill ticket that are not a colour card.
