Stitches, seams and processes

ZIMSEC O Level · Textile Technology and Design · Form 1, Form 2, Form 3

Hand stitches

  • Temporary: tacking (holds fabric before machining).
  • Permanent: running stitch, back stitch (strong), hemming, slip stitch (invisible hems), blanket stitch (edges).
  • Decorative: chain, stem, satin, cross stitch and French knots.

Seams

  • Plain (open) seam: the most common; neaten raw edges.
  • French seam: encloses raw edges; for fine fabrics.
  • Flat fell (double-stitched) seam: strong, flat; for jeans and work clothes.

Neatening raw edges

Zigzag stitch, overlocking, pinking, edge stitching, or binding.

Disposal of fullness

Darts, gathers, pleats and tucks shape fabric to the body.

Other processes

Hems (turned, machine, blind), facings and binding for necklines, fastenings (buttons and buttonholes, zips, press studs, hooks and eyes, Velcro), pockets, collars and sleeves.

Exam tip: Choose the seam for the fabric and garment – a French seam on denim would be too bulky.

Check yourself

  2. Which seam is best for jeans?
  3. Give two methods of disposing of fullness.
