My mother sent me these tiny vintage salt and pepper shakers for my "accented in red" kitchen. I hung them on this mail rack on the cabinet by the sink. I just love them! ... but I am trying to figure out why they are in the cute little red-checkered holster? Each shaker is about as big as your thumb. They are blue transparent plastic with aluminum lids. They fit into the fabric sleeves which are connected by a little strip of fabric. My theory is that they hung over something in a picnic basket, but I really have no idea. Does anybody know?
