I use a radiator-looking electric heater. They are energy efficient because once the oil is heated, electricity is needed only to keep it hot. It has a thermostat so you can turn it down when it gets to the "right" temp, and it will keep the room that warm. I couldn't work without it - it heats up the room much faster than the house heat.

My sewing room use to be a deck and there is no real heat and I use a space heater seems to work for me.

This sounds like a nice excuse to just cover all of your walls with quilts as insulation! Pretty and practical!

I have taken the time to read thru everyone's posts and there are at least 6 others who have mentioned the same product my family uses. The absolute BEST auxiliary heater is EDEN PURE. It is reasonable, a quartz heater, VERY SAFE and costs no more than an ordinary light bulb to heat up to 1500 sq. ft. I have two in my home and only spend $700 for a full year for oil for our furnace. There is no change in my electric bill. I've had two for over 5 years.
This is the one that Bob Vila advertises. My parents, my sister, a cousin and both my daughters all own at least one of these Eden Pure heaters. I always tell folks about them....they are the answer to your problem. Go to EdenPure.com and check them out. They come in two sizes....you will see which one will work best for your area - GOOD LUCK!!

I have one of those electric fireplaces, heats the room and gives the look of flames of a real fireplace with no mess. I have one that looks like a cast iron stove and one that looks like a fashionable fireplace. They look so real now.

I have the same problem....Want to go down and sew but it's too cold for me. Mine is a finished basement that is half carpeted but still cold. My dining room table is a mess now! lol

I use an electric heater named Vornado. Doesn't get hot to help protect pets and a thermostat. They run around 80 dollars, much less than Edan Pure. And I use it in my trailer for camping in the spring and fall. I just remember to unplug it like my iron when not in use.

I use the oil filled one from walmart on the front porch and warms up quickly and i don't worry about leaving it unattened with GBs

LOL. I think I was in denial. Surely after painting all the walls, applying an epoxy floor finish, moving in ceiling to floor bookcases and filling them with fabric, wouldn't the temperature go up at least a few degrees? Having the lights on, iron plugged in, and the machines humming would raise it another degree or two?:rolleyes: My internal thermometer runs a little higher than my DH, so I like it cooler. All of my extremities (toes, fingers, tip of my nose) were warm, so I wasn't concerned. But after sitting there for a few hours, I felt it in my back. Maybe I need more "insulation" (stash) down there.

Anyone know the R value of fabric? ;)

I feel your pain. My husband builds me a fire in the wood burner when I go down to quilt for the same reason. I am extremely cold natured and he bought me a little ceramic heater about 10 years ago. It really works well. I agree with the poster that said to put it on a power strip with a lamp so that you know it is off. This is what I do with my vintage machines so that I am not always trying to crawl under a table to unplug them.

I hope you can make your new space more comfortable. We have three ducts in our basement and my husband closes them for summer and opens them back up for winter (just because he is taller and can reach them w/out a step stool). A single duct to your area should be too expensive.

Good luck and keep stitchin'!
