A laminate for use in decorating a receptor surface (e.g., a window) comprising a piece of decorative sheet material with a layer of aggressive pressure sensitive adhesive on its rear surface and a release liner over that layer of adhesive; and a flexible, temporary support tape comprising a backing and a layer of repositionable pressure sensitive adhesive on a second surface of the backing. A longitudinally extending part of the layer of repositionable pressure sensitive adhesive of the support tape is adhered to a front surface of the decorative strip, and an elongate portion of the support tape projects transversely away from a first edge surface of the decorative sheet material. The repositionable pressure sensitive adhesive on that projecting portion of the support tape can be adhered to a receptor surface with the first release liner on the decorative sheet material laying along that receptor surface, and can be repositioned as needed to precisely position the decorative sheet material in a desired location. Once so positioned, the flexible backing can be bent along a longitudinally extending bend line along the first edge of the decorative sheet material to separate the decorative sheet material from the receptor surface so that the first release liner can be manually removed. The decorative sheet material can then be moved back into contact with the receptor surface so that its layer of aggressive pressure sensitive adhesive adheres the decorative sheet material against the receptor surface in the desired location, after which the temporary support tape can be peeled away.
