A recess 8 is provided with an undercut ii in order to frictionally retain an ornamental disc 12 when desired,

which is particularly applicable when both front and rear portions of the cover are made from flexible plastic material.

It is to be noted that the covers may be made in a wide variety of colors to harmonize with room decor and may be made in a variety of shapes to accommodate knobs of difierent shape and size, and that, in addition to decorative value, the cover may be made of suitable materials of desired thickness to serve as a bumper.
