identify the advantages and disadvantages of common natural and synthetic fibres (e.g., cotton is lightweight, breathable, and easy to find, but it can shrink when washed and is easily creased; silk is hypoallergenic, breathable, and strong, but it is expensive and the fibres are weakened by perspiration; spandex increases the stretch of a garment, but it is not breathable; polyester is relatively inexpensive and holds its shape and colour, but it is not absorbent, does not breathe, and can cling as a result of static electricity)
