Being that it's starting to get cold out and it's unpleasant to enjoy my cigars outside anymore (even here in FL since I smoke at night usually). I have an empty room upstairs and it has a 6x6 alcove in it with a window. Anyway, I need to seal of the 4th part of the alcove, but make it so that I can still get in and out of it. So a semi-permanent addition. I looked at thick curtains and shower curtains, but none we long enough. I want it to look descent, but not great. Any of you intelligent people have any ideas??
