GGI - Siria is a lightweight plain-woven cotton fabric with a loose and transparent texture.
In scenography it is normally used as a support, soaked in a solution of water and vinyl glue, to reinforce the surface of scenic elements or polystyrene sculptures.
It is also used for veils, transparency effects, costumes and props.
The same fabric stiffened with the vinyl solution is the GTR - Tarlatana.
