Last year it was unusually cold in southern california (I can hear the laughing from folks in the 'actual' winter states). I have no insulation in my workroom, twenty feet of single pane north facing windows and I do most of my sewing at night. I bought a small table and put it in the dining room over the heat grate! To handle quilting, I set up a wooden tray and put my big cutting mat on it. It supports the quilt and is easily removed and stored. It has worked so well that I have kept that table and machine up.
