Polyester curtain interlinings are sometimes called sarille interlinings. Using the latest synthetic fibre technology, they are lightweight and less prone to shrinkage in damp areas than cotton interlinings.

They work very well to give your curtains a nice amount of fullness and are particularly useful in light-coloured fabrics as they are white. They are also less expensive than cotton.

Overall an excellent choice for your curtains. Free samples are available — just fill in our contact form.
