OBSERVATION

Some candidates confused interfacing with facing in their explanation.

The expected answers are as follows:

(a)  Definition of interfacing

An interfacing is a layer of fabric sewn between the main garment and
facing/hem/collar.

OR

An extra piece of fabric placed between the garment and the facing.

(b)  Reasons for using interfacing/example for each reason

    (i) and (ii)      

  1. To prevent stretching e.g. collar, bands
  2. To make edge firm and strong e.g. edges of openings on blouses and jackets
  3. To give body or support to parts of garments e.g. pocket, collars, band.
  4. To make edges crisp e.g. collars and cuffs
  5. For reinforcing an area of a garment e.g. facings on openings, sleeve band, waist band.

(c)        Factors to consider when choosing an interfacing

  • Weight of fabric – the fabric of the interfacing must be lighter in weight than the fabric of the garment.
  • Effect required: Whether a firm tailored effect or a slight crispness is required – this will determine the type of interfacing chosen.
  • Durability of interfacing (compatibility) interfacing should have the same care treatment as the fabric used for the outer garment.

(d)       Fabrics used for interfacing

  • Organdie        
  • Lawn
