My curtains have lost their S fold.

If your curtains have lost their shape, simply tidy the S Folds by first drawing your curtains open. Then run your fingers from the top of your curtains to the bottom, forming neat folds that align to the S folds created in your curtain heading (top of your curtain). Our suggestion is to leave the curtain drawn open for a couple of days so that the fabric relaxes and remembers the folds.
