Blinds (Whittle Springs PR6)

2 'vision' day/night blinds, like picture but bigger. One is black and fits a window of 207cm wide and 130 cm high. The other is cream and fits a window of 173cm wide and 112cm high. If you are handy I think you may be able to make them smaller? Either or both. They work just a bit dusty and we wanted a full blackout since having a new street light fitted across the road :-(.
