An open weave jute fabric that is used for cleaning windows and for upholstery, and which makes great-looking sheer curtains. Scrim is transparent enough and discreet – the natural colour ‘disappears’ so that is not obvious from outside, and the material provides just enough coverage to shield. However, it is no good if you prefer your drapes neat and tidy or if you have cats or small children, as the open weave catches easily.
