Zardosi is very unique and elaborate art of embroidery done
in three dimensions. It is the heavy work used in coverings of all sorts
like heavy coats, cushions, curtains, animal trappings, canopies, shoes
and the kind. 
The ground material for zardosi is heavy silk, velvet or satin. The
artist first makes free hand sketches of this subject. Then he embroiders
in cotton threads over and over till he gets the required thickness and
movements.
Finally the artist takes the silk threads, twists them together in the
shades required for and embroiders with them the particular piece. In the
process, he creates original, unparalleled work of art. In this art form,
salma sitara, gijai, badla, katori, and seed pearls are used as per the
requirement of the fabric and the effect desired.
