i've got fluorescent lights... the door is open. I did open a window but sadly it felt just as hot outside as it was inside. We've got central heating & air. I think it just must be body heat and movement warming up the room. I'm okay with it warm. I like it warm but I felt bad for my friends. We'll just plan to wear short sleeves.. I started off with long sleeves and was ready for short sleeves very quickly. I have to remember to dress in layers. When my guild has Sewing Saturdays I dress in layers because you just never know...

Oh how I wish I had some of your heat in my upstairs nook. My frugal woman in me, just will not do it. In order to heat this room, I have to turn on another furnace that would heat 1200 other square feet of spare space (guest bedrooms, open hallways, etc). So I use a tiny space heater, and leave the door open as most of the hallway is open to the heatalor downstairs. Right now it is 60 degrees in here, feels almost warm.

These are all good ideas. I have a ceiling fan with a light on it.

excitement can make you get warmer. perhaps you should not get excited about what you are doing...especially with other people! NOT! enjoy! and i hope you find a solution.

My laundry room always seemed too hot and stuffy so DH installed a vent fan, the kind found in the bathroom. It works great to keep the room comfortable. That would be the less expensive way to go. It took DH about 2 hours to install it.

This is going to sound like a strange question - how much sun does the roof & walls of the room receive. We have a back bedroom and it receives a LOT of sunlight on the roof & one side wall. Our house is well insulated, but this room gets very warm in during Georgia's summers.
If you can't install a ceiling fan, at least try a floor or pedestal fan.

i have a small fan i use when it gets hot. i have no windows in my basement sewing room and it does get very warm at times.

I am usually too warm in my sewing room too. I have bare feet, legs, and arms while sewing. Now that it is winter my sewing room is set to 54 degrees which is perfect. Once I get the iron going the room is a comfortable temperature for me. Last summer was a different story! I moved a box fan so that it was blowing on me where ever I was working: the sewing machine, the cutting station, the ironing station, etc.. The fan really works to make me comfortable. I'm sure it is just blowing hot air on me but it is cooling none the less. I hope you find a solution - I really hate being too warm.

My studio was always really warm until my husband changed out the lighting for me. I had regular fluorescent fixtures in there and they are hot. He changed them out with the new T8 fluorescent fixtures and bulbs. I can't believe the difference. The room is not hot any more and the bulbs are brighter. I know it sounds silly that it could make that much difference but it does. Please try it.

Check with Lowes or Home Depot and get "COOL" lights. Maybe put an oscillating fan (vertical type) on an upper shelf to cool the warm air. Remember warm air rises, so if you cool it off closer to the ceiling the cool air will drop.
