I still have 'temporary' curtains on a pole that I got from the Homebase sale section 8 years' ago for about £8. Been meaning to get something since but undecided what to get. I want the room as dark as possible and love the European shutters that close from the outlet side (either automatic or manual) but they don't seem to do anything like that in the UK. Will plantation shutters block out the light? It is quite a small window 70cm height x 90 cm width. What is the best way to keep out the light?
