Headed for 17 tonight. Not sure what we hit during the power-out, but it was 20’s-like. Thank goodness this place is insulated.

The blackout liners we got because of the glare-prone old telly—really made it possible to keep this living room warm. Magnetic closure means no light. WE just have these mysterious little points of light—kitty help.

You just put them on the same hook as your regular window drapes, granted you have regular window drapes. One of the best investments against overheating in summer or chilling in winter.
