I understand the problem. All 3 of the rooms I sew in, especially the one with the longarm are lit up like the surface of the sun. I found a large wire cage fan with "more power" tipped up toward the ceiling to help circulate all the air in the room to be more effective than one blowing directly on me. You also might try a fan blowing out of the doorway to pull the heat out of the room. Also a damp towel around the neck or a cooling neck wrap for freezer from drug store. I also vote for as few clothes as possible.
