Construction and Garment Assembly
Construction and Garment Assembly
This domain tests how fabrics are cut, joined, shaped and finished in a logical order. Expect questions on seams, hems, closures, pressing and assembly sequences.
Core rules
- Seam choice follows fabric and purpose: plain for stable woven, French for sheer/light, overlock for knits, flat-felled for denim and workwear.
- Order of assembly usually: prepare pieces → darts → seams → closures → facings/waistbands → hems → pressing. Some steps move earlier for lined or reversible garments.
- Pressing is part of construction, not finishing: press as you sew to set stitches and remove bulk.
- Clipping curves and notching corners allows seams to lie flat; do not clip through stitching. Seam allowance must match the pattern.
Worked example
For a cotton tote with a zip pocket, sew the pocket and zip before joining the side seams; otherwise the bag is closed and the machine cannot reach. Reason: assembly order preserves access and prevents bulky handling.
Traps
Sewing a hem before fitting; clipping a curve too far; using a straight stitch on knits without stretch; pressing a synthetic at too high a temperature.
