We have arrived on holiday and I have forgotten our black out blind to stick on the window. Our caravan was so hot and bright and our 7 month old would not sleep until 9pm and then awake at 4am. Our 5 year old struggled too. What can we use temporarily to stick on the windows? Bin bags? Tinfoil? We are in a private caravan so don't want anything that could damage or leave marks. We are off to Tesco today. I have already checked Facebook market place and no luck! Thank you xx
