I recently bought some blackout curtains from John Lewis and I’m in love with them! However the sunlight leaks out from the top which I find so annoying! Is there something you can buy to block it? I’m currently using towels to stop the sunlight from leaking through which helps but it’s a temporary solution as I’d want something nicer.
I was looking at cornices (I’ve only seen them in hotels) and nowhere seems to sell them? Is there anything else?
