Cold Air Stopper from a Pant Leg

You can easily make a cold air stopper with stuff you have at home, works great to stop cold air drafts from underneath doors.
My sister made this one for me, just an old jean pant leg filled with stuffing and a couple bags of dried beans, sew up the ends and you've got a Cold Air Stopper. When it's warm out and I don't need it anymore I just hide it under a bed until I need it again.
