How to make a fabric cover for dish

Once upon a time we used to use cling film, or plastic wrap, and then the more sustainable folk started using fabric wax wraps. (there is a course on our website). I find fabric food covers more hygienic, as you can wash them at 30 degrees without them turning into a ball of wax, and they don’t stain like the fabric wax wraps do. Also, you can make them with scrap – and if you ask around I am sure you can find someone who has some elastic they can spare.
