In this electrical age there are few household appliances more valuable
than the electric sewing machine. Sewing then becomes a positive pleasure ;
you just plug into a lamp socket or wall plug, and switch on. Both hands
are free to guide the work, and the speed of the machine, which is regulated
by gentle pressure on the speed controller, may be varied at will to suit the
work in hand. For example, the machine may be controlled to run at a low
speed when sewing a short length of seam, or where great care must be taken
in guiding the material. On long seams the speed of the electric machine is
much greater than is possible when working by hand or foot treadle.
It is not necessary to touch the wheel, as the machine will always start
in the right direction.
