My long arm lives in the basement, during colder periods, I use my rotating space heater. I have it up off the floor a bit and it blows the heat on my legs and feet. Feels good! I usually do dress a bit warmer, and I have some of those wool gloves with just finger holes which keeps my hands warm. During the snowier parts of the year, the two basement windows will be covered by snow and yep, it really is a quilting cave then. I do sometimes call it the quilting dungeon too.
