I read somewhere that you can add a layer below a background layer if the background layer is transparent. (I could not find the site again else I would not have asked the question.) I made a background layer transparent I think (the chequerboard shows) but could not slip in any layer beneath it. Is it possible at all or is it that I misunderstood that a layer below a transparent background layer can be added. If possible, then what mistake I might be making. I have searched the topics with 'transparent background' but could not find the answer. Could somebody help please.
