Insulation wanted

This is shaping up to be another season where all my design choices are dictated by how cold I am. I am 'frileuse'*, and cold winters in an old house call for fuzzy layers. It used to be worse - I lived in an Old Montreal loft in the early nineties and one winter was particularly harsh. The pipes in the loft below burst on boxing day, and the firemen came to the rescue (not that anyone complained about that!). The building was so badly insulated, you could actually see outside through cracks in the brick... But it was cheap, and we had oodles of space for set and costume design.So. The mittens are done, but the pattern isn't. I have a deadline to attend to first, and will cast on a simple cozy sweater this weekend. All of my secret projects demand some thought, so it'll be nice to have a little stockinette piece on the go. Actually, not too little - I'm cold.*sensitive to the cold; I don't know of an equivalent english word - do you?
