Abstract A hand-operated sander which can be used to sand both sides of a louver (front and back) simultaneously. The louver can be part of a shutter, folding door, blind or any other louvered object. The sander consists of two elongated flexible members which are hingedly secured to each other at adjacent ends. Each member is adapted to detachably receive sandpaper. In use, one sandpaper carrying member is used in sanding one side of the louver while at the same time the other sandpaper carrying member is used in sanding the other side of the louver. A louver edge sander can be incorporated into the remainder of the structure described above whereby the edge as well as both sides of the louver can be sanded at the same time.
