I can't search the archives as search is switched off but after yet another 5.30am start we really, really do need blackout. What's best? Should we get John Lewis light stop curtain linings? or do they not stop all the light? We have pole curtains so surely some light would come through still? Would just black sugar paper do the trick? I don't care about not being able to open the windows, I just want some sleep! Surely that's going to end up being cheaper and easy enough? I've looked at darkroom equipment curtains but they seem expensive. Any ideas welcome. We have John Lewis and Ikea near enough and I need to get something today.
