Overall these are some very nice curtains.  The blue is wonderful and the curtains certainly do help insulate the room.  They block out almost all the light and although a little does sneak through, I would highly recommend these even for a bedroom.  I went with the 72" length which worked well because it hangs well below the windows but stays up off the ground.  I wish more curtains came in that length!

Nice curtains at a solid price - highly recommended.
