A swag is a shape of fabric which is pleated, draped and fixed to a pelmet board. Two or more swags can be made to fit across the width of the pelmet board and can overlap each other or butt together with tasseled tails in between as well as at each end.
Like pelmets and valances, swags and tails need to be in proportion to the rest of the window treatment with the swags approximately 1/6th of the length and the tails between 1/3rd and 2/3rds the length of the curtains.
Tails overlap the end swags in order to finish the treatment and conceal the sides of the pelmet board - These are pleated so that the lining shows from the right side and therefore need to be backed in a contrasting or co-ordinating fabric.
