I have some kind of issue with staying in one position too long. I begin to stiffen, and it has (once!) gotten to the point I was stuck in a chair until DH came home. I set up my sewing room in areas. (Kind of like my kindergarten classroom was divided into activity areas.) sewing is in front of a window, on an old teachers desk, with a low office chair, ironing in the corner, cutting in the center of the room, cat perch in another corner so they can watch like the vultures they are lol, and two large dogs sprawled in what ever walkway I need to use next.... I move constantly to avoid the stiffening. Sew, iron, sew, iron, sew iron, better than aerobics.
