Abstract: An inflatable ornament suitable for hanging on a Christmas tree limb or the like is formed from a pair of flexible plastic sheets joined along their periphery to define a collapsible, substantially fluid-tight envelope. The envelope includes a reduced neck portion having a valve therein for filling the ornament with a suitable fluid such as air. The valve comprises a stem extending laterally outward from one of the sheets and a removable plug for sealing the stem. A hook member connected to the stem, or formed integral with the plug, is adapted to suspend the ornament from the limb. A reflective metal coating applied to the envelope gives the appearance of a glass ornament.
