Happy window, happy room
Pretty blankets can go a long way.
My bedroom, despite having only one window, is easily flooded by daylight. Having the head of the bed right under it (feng shui aside) is not a fun place to sleep in. This gets worse when (1) I have less than seven hours of sleep, and (2) The sun's blinkin' high, filling the room with light.
Well, we fixed that.
That up there is a flannel blanket fixed to the metal window frame with two powerful hard-disk magnets. We used this trick back in the day when we enjoyed sleeping on the cooler first floor of the house.
I like our bedroom now, I really do. It gives the room a nice warm glow. It's also not too hot in the afternoon. At night, the room is pitch-black. It keeps the room pretty dark even at five o'clock in the morning, making it easy for me to get some decent shut-eye.
I think the only puzzled member of the household would be Mink. Here she is, puzzling over how to get to them fun climbey grid window irons.
