Claim:
A lampshade system comprising: a lampshade formed of a flexible substantially flat, unpleated and light transmitting plastic sheet having a printed pattern thereon, the sheet including interengaging releasable attachment elements on opposing edges of the planar sheet so that the sheet may be rolled into a tube and retained in tubular form by the attachment elements with the opposing edges proximate and the attachment elements interengaged, and so that subsequently the attachment elements may be disengaged and the tube unrolled into a flat sheet; and at least one releasably attachable lampshade spider collar component having a ring element receivable around a lamp element to be supported thereby and having arms extending radially from the ring; wherein said flat sheet further includes at least three holes passing through the flat sheet and engaging ends of corresponding arms when the flat sheet is rolled into a tube to support the tube coaxially about the lamp element when the ring element is received around the lamp element, the lampshade and spider collar attaching so that weight of the lampshade is supported at the contact between the arms and the at least three holes; wherein the arms each provide a corresponding lampshade retention element positioned at a tip of the arm away from the ring element, the lampshade retention elements each providing a vertically extending surface fitting against a corresponding surface of the lampshade to hold the lampshade substantially centered around the ring element when the arms are fit through the holes.
