    Guides students through threading, tension adjustment, and basic stitch selection on domestic and industrial machines. Builds machine confidence before garment work begins.

  • Lesson 4 • Fabric Knowledge and Selection

    Teaches fibre types, weave structures, and fabric properties relevant to garment construction. Students match fabric characteristics to garment requirements.

  • Lesson 5 • Workspace Setup and Safety

    Defines ergonomic layout, lighting, and safety practices for a professional sewing workspace. Proper setup prevents injury and supports efficient workflow.

Chapter 2See details

Body Measurement and Pattern Drafting

  • Lesson 1 • Pattern Drafting Tools and Materials

    Introduces drafting tools, pattern paper types, and notation conventions. Students set up a drafting station and practise using rulers and curves accurately.

  • Lesson 2 • Drafting Skirt and Trouser Slopers

    Applies measurement-to-pattern skills to lower-body blocks. Students draft straight skirt and basic trouser slopers with correct crotch curves.

  • Lesson 3 • Drafting the Bodice Sloper

    Step-by-step construction of a fitted bodice block using personal measurements. The bodice sloper becomes the foundation for all upper-body garment patterns.

  • Lesson 4 • Taking Accurate Body Measurements

    Teaches the full sequence of body measurements needed for garment drafting. Accuracy here directly determines fit quality in all subsequent chapters.

  • Lesson 5 • Sleeve Block Drafting

    Covers one-piece and two-piece sleeve block construction with correct sleeve head ease. Students learn to match sleeve cap to armhole before proceeding to garment work.

Chapter 3See details

Pattern Manipulation and Grading

  • Lesson 1 • Dart Manipulation Techniques

    Teaches slash-and-spread and pivot methods to move and combine darts for design purposes. Mastery of dart manipulation unlocks a wide range of bodice styles.

  • Lesson 2 • Adding Style Lines and Design Details

    Covers princess seams, yokes, and panel lines derived from the sloper. Students learn to separate pattern pieces and add seam allowances correctly.

  • Lesson 3 • Pattern Grading Fundamentals

    Introduces grade rules and nest grading to scale patterns up and down across standard sizes. Students produce a three-size nested pattern set from a base size.

  • Lesson 4 • Pattern Preparation for Cutting

    Covers pattern marking, layout planning, and fabric preparation before cutting. Correct preparation reduces fabric waste and cutting errors.

  • Lesson 5 • Flare, Volume, and Fullness

    Applies slash-and-spread to add flare, pleats, and gathers to skirts and bodices. Students calculate the correct amount of fullness for different fabric types.

Chapter 4See details

Core Hand and Machine Sewing Techniques

    Teaches basting, slip stitch, catch stitch, and pad stitch used in tailoring and dressmaking. Hand stitching skills support fitting, finishing, and tailored construction.

  • Lesson 2 • Seam Types and Construction

    Covers plain, French, flat-felled, and lapped seams with correct pressing at each stage. Seam choice is matched to fabric type and garment end use.

  • Lesson 3 • Pressing Techniques in Construction

    Establishes pressing as an active construction step, not a finishing task. Students press seams, darts, and shaped areas correctly at every stage of assembly.

  • Lesson 4 • Stitching Curves and Corners

    Develops control when sewing concave curves, convex curves, and sharp corners. Students clip, notch, and grade seam allowances to achieve smooth, flat results.

  • Lesson 5 • Seam Finishing Methods

    Teaches overlocking, zigzag, bound, and Hong Kong finishes to prevent fraying. Students select the appropriate finish based on fabric weight and garment quality level.

Chapter 8See details

Tailored Garment Construction

  • Lesson 1 • Tailoring Fabrics and Interlinings

    Covers wool, tweed, and suiting fabric preparation alongside canvas, domette, and tailor's linen. Correct interlining selection determines the structure and longevity of the garment.
