ABSTRACT:
A universal foldable lamp shade cover which includes a uniformly pleated rectangular sheet of thin, somewhat rigid yet bendable material having a plurality of side-by-side slender elongated panels integrally connected one to another in accordion fashion along a fold line between each panel. The side margins of the pleated sheet are connected to form a somewhat tubular member which is sized, when reduced in circumference at its upper end, to be held in place primarily by a strip of double-sided adhesive tape adhered on one side around the upper perimeter opening of a lamp shade. The lamp shade cover is then adhered in position over the lamp shade to the exposed surface of the adhesive transfer tape.
