I'm glad I'm not the only one with a hot craft room.
My room gets the sun all day long. It comes up behind the house and just moves across the sky, behind the house... That's got to be a main culprit that I had not even thought of...
I also love the idea of installing ceiling vents. that might really help a lot.
I do have the T8 fluorescent lights. I think it must really be the iron, the sewing machines and three women all moving around that put it over the edge. Hubby has come in here and said wow, it's hot in here and he isn't meaning me lol.
I'm sure something will give. I love the suggestions that everyone is giving. I'm going to bounce some off of my father in law (he's the handy one. My husband is not - hanging a picture is a big ordeal for him lol) and see if he has any ideas on what I can do to fix it.
