Lunch bags and cool totes.
Cool totes are for people to take their frozen food home in during the hot summer months.
You take fabric and the vinyl that presses into the fabric, this is the inside of the bag. Layer insul-brite, foil side in and regular fabric on the outside, quilt together. Sew like a Tote bag and put a piece of velcro on top or a zipper.
Lunch bags are made the same way, except the size is more like a paper sack.
