Alex, thankyou for that, I was wondering whether it was a pre-made product.
Rob I did try wrapping in silicone baking paper, then foil, but as Alex explained, the cheeses need to breath, and these couldn't, so were wet, and stinky when I finally checked them. So now I just wrap in foil.
Actually the special papers that I just purchased were plastic on one side, paper on the other, with tiny perforations, and I was wondering whether freezer paper that is used for quilting could be used, as it is plastic on one side and paper on the other. I might give this a go in the future.
