I have put all the necessary tapes in place. My room is facing where the sun shines bright in the morning and wakes me up my warming my buns. Ive only put it up once. But I will be putting it up more often for the night before the sun comes out and I have to jump out of bed at 6 am. I'm 70 years old and think I've worked hard all my life so I do deserve more sleep. Plus I've moved upstairs in October loved the sunshine all around the house. Because I lived downstairs for two years in the dark my windows 3 sizes of less than 12 inches wide and one in the washroom of 7 inches wide so now I also have to use two airconditioning systems.
