It's so nice to know I have company ... I am, by far, the hottest person in our household. Everyone else is always freezing and I am always roasting. I vote for the air conditioner - I know I would definitely use it - oh wait, I share my sewing room with my husband and his hobby - or is it the other way around? I keep forgetting - lol.
I always tell him he can put on a long-sleeved shirt or a sweatshirt - I am not going to sew naked - that would be such a scary sight - and that would be the next step for me without a window unit.
