Abstract
A fabric covering is applied to the body or frame of a lampshade, which frame has a lower circle (ring) and an upper circle (ring) disposed with a common axis and connected by a plurality of angularly spaced struts. The two ends of the fabric covering are held in place by a pair of axially spaced members and these members are urged apart to stretch the fabric against the frame. The fabric is then glued to the elements of the frame and excess fabric is cut away above and below the frame.
