MANUFACTURING INSIDER SERIES

50 pages, 11 chapters.

Most tech packs that land on White Cotton's cutting table are missing the same three things, every time. The Tech Pack, Page by Page closes that gap — the complete path from flat sketch to cutting table.

Its chapters cover what a tech pack actually is (the seven sections every complete one contains, and the real cost of a bad one — €300–500 in wasted sample iterations), garment anatomy and factory terminology, measurements and grading across S–XXL with tolerance specifications, fabric specification down to GSM and Pantone TCX lab dips, and construction detail including six seam types with ISO 4916 stitch codes.

As the book's own line puts it: "a €200 investment in getting your tech pack right saves €300–500 in sample iterations and 30+ days in development time." 47 pages of factory-tested specification knowledge.

A complete tech pack quoted and sampled in 17 days, start to finish, from our own production data. Real 2026 sample invoices ran €130–190 — an avoidable re-round buys another.

Table of contents

What's inside.

01

What a Tech Pack Is (and Isn't)

A production manager has ten minutes to extract everything needed to source fabric, cut pattern pieces, and schedule the line. Miss a section and they email you — or they guess.

  • · The 7 core sections every complete tech pack needs
  • · What happens when each section is missing: a 2–5 day clarification email, or a factory default
  • · Why a tech pack is a manufacturing instruction set, not a mood board
02

Garment Anatomy

You can't specify what you can't name — describe 'the ribbed part at the bottom of the sleeve' and the factory has to resolve the ambiguity on its own.

  • · What every flat sketch needs: front, back, detail and internal-construction views
  • · Callout rules — leader lines, numbered references matched to the Bill of Materials
  • · Factory terminology for every component, by garment type
03

Measurements & Grading

A size chart specifies finished garment measurements, not body measurements — the gap between the two is called ease.

  • · Ease ranges by fit: Slim +2–4cm through Oversized +13–18cm
  • · How grading scales a pattern between sizes
  • · Tolerance specifications, tight to relaxed
04

Fabric Specification

'I want a nice cotton' is not a fabric specification. Weight, composition, construction, shrinkage and color — miss one and the factory is guessing.

  • · GSM by fabric type: jersey, French terry, fleece, piqué, rib, canvas/twill
  • · The five properties a real fabric spec needs, not GSM alone
  • · The six fabric structures behind the weight table
05

Construction Details

Two identical-looking hoodies. One falls apart after five washes, one lasts five years. The difference is in the seams.

  • · 6 seam types with ISO stitch codes, from 4-thread overlock to chainstitch
  • · Stitch density (SPI) standards by fabric weight
  • · Where each seam type belongs — high-stress, hems, topstitching, activewear
06

Trim & Labels

The €0.30 label is the first thing a customer touches inside the garment — and a legal requirement under EU Regulation 1007/2011.

  • · What's legally mandatory on an EU label vs commercially essential
  • · 5 label types compared on cost per unit, from printed satin to silicone
  • · Label placement by position on the garment
07

Artwork Placement

'Center chest, big' is not a placement specification. '18cm wide, 8cm below HPS, centered on body width' is.

  • · Reference points: HPS, CF, CB, side seam, armhole seam
  • · Standard placement positions and typical sizes, left chest to full back
  • · One spec that produces consistent garments instead of surprises
08

The 12 Mistakes

The dozen most expensive tech pack errors, by root cause — from missing tolerances to no sealed sample.

  • · No tolerances, no grading, wrong fabric weight, RGB instead of Pantone
  • · Missing wash data — an unwashed garment can shrink 5%, turning your M into an S
  • · Label content errors that get flagged at customs
09

Your First Tech Pack

You've read the theory. Here's the nine-step build, zero to production-ready.

  • · Start from a reference garment, build the flat sketch, create the size chart
  • · Specify fabric, construction, trims and artwork placement in sequence
  • · Review against the Chapter 1 checklist before you send
10

The Sample Round

Sending the pack isn't the finish line — it's the starting gun. A dated, real sample round from our own order log.

  • · A first-time client's boxy tee, quoted and sampled in 2026, every date real
  • · What happens in the loop between quote and shipped sample
  • · Why a complete pack gets priced without a single clarification email
11

Your Tech Pack, Page by Page

Six fill-in drawing sheets, the same structure our studio outputs and our cutting table receives — reproduced as a template.

  • · Style header & flat sketch, and five more sheets covering the full spec
  • · Print-and-fill rules: one set per style, title block on every sheet
  • · A complete pack any knitwear factory in Europe can quote and cut from
