A very thin thread's strand called yarn from which cloth is made is called a fibre. Fibres are woven to make fabrics such as cotton fabric and silk fabric.
Natural fibres are a collection of tiny threads obtained from plants and animals.
Cotton, wool, silk and flax are among the natural fibres used to make clothes.
Clothes made of cotton fabrics are worn during the hot days of summer.
Clothes made of wool are worn during the cold days of winter.
Clothes made of silk are most comfortable when the weather is neither very hot nor very cold.
Fabric made of flax is called linen and is used for making bed sheets, shirts, etc.
