4. Purpose and use of the garment: For school uniforms, casual wear, sports wear etc. select simple collar designs without decorative details. Flat collars are more comfortable than standing or roll collars and are therefore advised for garment like casual wear.

b. Growth and Production: 1. Cultivation: The flax plant requires deep, rich, well plowed soil and a cool, damp climate. Prematurely warm weather affects the growth and the quality of the fiber. As soil in which flax is grown must be enriched for six years before it will yield a good harvest, only one crop in seven years can be raised on specified portion of land. The flax seeds are sown by hand in April or May. In three months the plants become straight, slender stalks from 2 to 4 feet in height, with tapering leaves with small blue, purple or white flowers. The plant with the blue flower yields the fine fiber. The others produce coarse but strong fiber. After flowering mature plant develops seed capsules in the size of peas. The seeds are about 2 mm long and are very rich in oil.
