There are methods to ensure your cushions made of linen dry out completely even when air drying. You should start by placing them on a clean, dry and flat surface or, if you want, you can also hang them. There are some best practices to consider when it comes to drying also: keep them away from direct sunlight to minimize the chances of decolouration and make sure the area you keep them is well-ventilated to speed up the drying process.
