<P> Khadi or hand - spun cloth is the only material allowed to be used for the flag, and flying a flag made of any other material is punishable by law with imprisonment up to three years, besides a fine . Raw materials for khadi are restricted to cotton, silk and wool . There are two kinds of khadi used: The first is the khadi - bunting which makes up the body of the flag, and the second is the khadi - duck, which is a beige - coloured cloth that holds the flag to the pole . The khadi - duck is an unconventional type of weave that meshes three threads into a weave, compared to the two threads used in conventional weaving . This type of weaving is extremely rare, and there are fewer than twenty weavers in India professing this skill . The guidelines also state that there should be exactly 150 threads per square centimetre, four threads per stitch, and one square foot should weigh exactly 205 grams (7.2 oz). </P> <P> There are four places in the country licensed to make the cloth for the national flag, they are in Karnataka, Marathwada, Barabanki in UP, and Banetha in Rajasthan . The woven khadi is obtained from two handloom units in the Dharwad and Bagalkot districts of northern Karnataka . Currently, Karnataka Khadi Gramodyoga Samyukta Sangha based in Hubli is the only licensed flag production and supply unit in India . Permission for setting up flag manufacturing units in India is allotted by the Khadi Development and Village Industries Commission, though the BIS has the power to cancel the licences of units that flout guidelines . The hand - woven khadi for the National Flag was initially manufactured at Garag, a small village in the Dharwad district . A Centre was established at Garag in 1954 by a few freedom fighters under the banner of Dharwad Taluk Kshetriya Seva Sangh and obtained the Centre's licence to make flags . </P> <P> Once woven, the material is sent to the BIS laboratories for testing . After quality testing, the material, if approved, is returned to the factory . It is then separated into three lots which are dyed saffron, white and green . The Ashoka Chakra is screen printed, stencilled or suitably embroidered onto each side of the white cloth . Care also has to be taken that the chakra is completely visible and synchronised on both sides . Three pieces of the required dimension, one of each colour, are then stitched together according to specifications and the final product is ironed and packed . The BIS then checks the colours and only then can the flag be sold . </P> <P> Display and usage of the flag is governed by the Flag Code of India, 2002 (successor to the Flag Code--India, the original flag code); the Emblems and Names (Prevention of Improper Use) Act, 1950; and the Prevention of Insults to National Honour Act, 1971 . Insults to the national flag, including gross affronts or indignities to it, as well as using it in a manner so as to violate the provisions of the Flag Code, are punishable by law with imprisonment up to three years, or a fine, or both . </P>
