Empty ostrich eggshell, in different shapes, colors, painted or simple, for decorating . Intricate cutting of an empty eggshell is accomplished by applying over and affixing to the surface of the shell a fine cord, or braid, in a manner so as to produce an artistic design, and cutting out portions of the eggshell bounded by the cord by inserting a drill bit into and within the eggshell and cutting laterally with the drill edge along the boundary of the portion formed by the cord until the enclosed portion is completely cut out.
