a) Some undesirable properties of viscose rayon include its tendency to shrink when washed, its low elasticity, and its weakness when wet. Additionally, viscose rayon is prone to wrinkling easily and can lose its shape over time.

b) Features that can be used to finish a night dress decoratively include lace trim, embroidery, beadwork, ruffles, ribbon detailing, or decorative buttons. These features can add a touch of elegance and style to the night dress.

c) Ironing a night dress during construction is important to ensure a professional and polished finish to the garment. Ironing helps to smooth out any wrinkles, creases, or puckering in the fabric, allowing the night dress to drape correctly and look its best when worn.

d) Desirable qualities of an iron box include a sturdy and durable construction, a smooth and non-stick soleplate for easy gliding, adjustable temperature settings for different types of fabrics, a steam function for removing stubborn wrinkles, and a long power cord for maneuverability. Additionally, an iron box with a self-cleaning feature can help prolong the lifespan of the appliance and ensure consistent performance.
