Falduri concentrice

The falduri concentrice is a method for draping fabric artifacts with curvilinear pleats.
Their succession starts from a more or less wide arc of circumference whose radius is progressively reduced.
The falduri concentrice is used above all for the making of valances of velvet main curtains with a solemn appearance, sometimes even pompous, or with an elegant look.
With lighter or brighter fabrics, one can make up borders of theatrical sets having a more lively look or simple decorative valances can be made up too.
Sometimes a single large drapery can assume the importance of a main curtain.
