Well... you're in SC so this might not apply, but... anyone up north might be able to identify with this.
My first apartment was on the second floor flat of an old city house. It had a lovely porch off the living room, with a drafty old door and two equally drafty windows facing west (toward the wind). The landlord was cheap so there were no storm windows or other insulation.
Now, whenever the winter weather blew in, the temperature in the living room was six degrees colder than in the next room over. So I decided I would take my stash, and hang it from the curtain rods, over the windows and across the door. Yes, the room was very dark, but I was able to raise the temperature three degrees AND play with my fabric at the same time.
(Still living outside Buffalo NY... need I say more?)
