This sheer, square, black spider web table cover is a great decorative piece. The spider web design and the four spiders on the corners (one in each corner) have a velvet-like feel, and as a result, the table cover looks good by itself or on a colored tablecloth or surface. There is wiring and a black box for batteries attached to the back side. The wiring is hidden, but the black box can be seen through the sheer fabric. The box takes three AAA batteries and needs two mini screwdrivers to open it - a Philips screwdriver to remove the tiny screw and a flathead screwdriver to remove the battery cover. There is an on/off switch on the back of the battery box to activate the six lights that form a circle in the middle of the web. The lights glow, flicker, and flash in yellow, red, green, and blue. The edge of the table cover is sheer and is cut to outline the shape of the spider web. The edge is not sewn, but since it has one to two inches of sheer material beyond the spider web, it can be trimmed easily if it frays. It is not machine washable due to the wires and battery case, so I would recommend using it on a table for decorative purposes rather than where food or beverages would be placed.
