Explains lengthwise grain, crosswise grain, bias, and selvage edges. Grain alignment directly affects garment drape, fit, and durability.
Lesson 3 • Fabric Care Labels and Standards
Decodes international care symbols and fibre content labelling requirements. Students learn to advise clients on garment care based on fabric composition.
Lesson 4 • Fibre Content and Fabric Structure
Covers natural, synthetic, and blended fibres alongside woven, knit, and nonwoven structures. Understanding structure determines how fabric behaves during cutting and sewing.
Lesson 5 • Fabric Weight, Drape, and Hand
Teaches how to assess weight, drape, and tactile quality to match fabric to design intent. These properties determine which sewing techniques are appropriate.
Chapter 3HideHide detailsSee detailsHand Sewing Techniques
Hand Sewing Techniques
Lesson 1 • Threading and Knotting Techniques
Covers threading a needle, cutting thread at the correct length, and forming secure knots. These basics underpin every hand-sewing task in the course.

Explores the blanket stitch, cross-stitch, and bar tack for finishing and reinforcement. These stitches add professional detail and structural strength to garments.
Lesson 5 • Backstitch and Whipstitch
Introduces the backstitch for strong seams and the whipstitch for edge finishing. Both stitches appear in repairs, closures, and hand-finished seams.
Chapter 4HideHide detailsSee detailsSewing Machine Mastery
Sewing Machine Mastery
Lesson 1 • Anatomy and Threading of the Machine
Identifies every machine component and demonstrates correct upper and bobbin threading. Proper threading is the single most common source of stitch problems.
