different types and sizes of buttons. Especially there may two or three holes in the button. Again
button of three holes may be attached by parallel or cross sewing. Buttons may be of different
types specially there may be shank below the button or during sewing shank may be made by
thread. For sewing button lock stitch, chain stitch or hand stitch machine may be used. When
using chain stitch the sewing looks neat below the button but the safety of stitch is low that is the
button may be fall out opening the sewing. This will not happen when used lock stitch but it is not
as neat as chain stitch. In automatic machine by a hopper and pipe button is fed in button clamp in
