Sew naked
I couldn't resist.
The flourescent lights don't give off much heat. The iron does. I'm at that wonderful age when all of a sudden I've become my own whole house heater. This is all relatively new to me ... a voyage of discovery. I have noticed certain triggers though. My iron IS indeed one of them. When I'm using it ... hot flashes. Another trigger is a "flurry" of activity. If I've had my iron on all day I can definately feel the differnce in the overall temperature of the room.
