Does anyone know what benign of curtain that have rings sewn on the hindmost, and you verbs it up beside a cord? It is kind of a square piece if stuff with rings...

It is kind of a square piece if stuff with rings sewn contained by lines, and you pull it up near cords. It forms nice folds of fabric when fully pulled up. I regard as it may be roman shade, but I am not sure.
Answers:    Roman shades have slats contained by them to produce straight, horizontal folds. Austrian shades, aka Austrian curtains, have rings but no supports, and kind curved swag shapes when pulled up.
