If one of the windows in your house or apartment lets in far too much cold, noise or light at night, thin store-bought curtains won’t do much to block it off. A thick-but-manageable Roman shade might be just the solution.
One Instructables user lives where it gets cold enough that “when you look at the framework … there’s ice all over it”. To kill the drafts, and block out some light and noise, they created a fold-down Roman shade, made of a fleece throw that was warm but not so heavy as to be an annoyance to hoist back up in the morning.
It’s not a one-hour project, and it involves a sewing machine and a drill/powered screwdriver. It’s also not a replacement for getting a more energy-efficient window installed.
