Practical Work
What the exam tests
Practical Work assesses safe tool use, measurement, drafting, cutting, machine sewing, pressing and finishing. Examiners look for accuracy, neatness, correct sequence and a clear record of the process.
Core rules and concepts
- Prepare the workstation: clean machine, correct needle and thread, wound bobbin, sharp scissors, pins, tape and chalk.
- Measure accurately and draft true patterns. Check grainline, notches and seam allowance before cutting. Cut on a flat surface with the fabric supported.
- Sew a test sample first. Check stitch length, tension and seam allowance. Backstitch at seam ends where strength is needed.
- Press seams as constructed. Trim and grade allowances to reduce bulk. Finish raw edges and inspect inside and outside.
- Record tools, measurements, samples, faults and corrections in the practical file.
Worked example
A machine makes 12 stitches per inch. Stitch length in millimetres = 25.4 ÷ 12 = 2.12 mm. For medium cotton shirting, about 2.5 mm or 10 stitches per inch is suitable. Adjust the machine to 10 stitches per inch and test on a scrap. The reasoning is that stitch length affects seam strength and appearance: too short weakens the fabric, too long leaves gaps. The test piece proves the setting before the garment is sewn.
Traps that cost marks
Cutting off grain, using a loose tape measure, sewing without a test sample, trimming seam allowance too close, and failing to press at each stage cost marks.
