A husk swag looks simple - a row of little bellflowers hanging in a curve - and it is the element most often got wrong.
Two things have to be right. The first is the curve itself. A swag drawn freehand nearly always comes out too shallow at the ends and too round in the middle, which reads as a smile rather than as something hanging. Our artisans hang an actual light chain between the two fixing points on the setting-out board and trace the curve it makes. That is the only shape a hanging thing takes, and the eye knows it immediately even if it could not tell you why.
The second is graduation. The husks are largest where the swag hangs lowest and diminish steadily toward each end - not by a fixed step, but proportionally, so that the row appears to recede up the curve. Cut them all the same size and the swag looks like beads on a wire.
Get both right and a strip of carved wood convincingly hangs off a flat frame. That is the whole illusion this style depends on.
