I've always wanted to put up those blue christmas lights around the ceiling in my bedroom. they are so relaxing. I had some for my tree a couple years ago but they already crapped out, they were cheap plastic ones I paid next to nothing for haha. When I was a kid I always loved the blue ones best. Back in the 60's we had the big glass christmas light strands or whatever in a variety of colors and I remember leaving my curtains open in the middle when i went to bed so i could see the blue ones.
