It is a deliberate design choice that defines the Jupiter collection. While standard sheers can be extremely light and prone to fluttering, "Heavyweight" refers to the fabric's substantial density. This added weight allows the curtains to hang beautifully straight , creating deep, fluid folds with a sculptural quality. They feel rich to the touch and anchor the room with texture, offering that custom, designer-grade aesthetic while still maintaining an airy, light-filtering appeal.
