Abstract: A versatile wall decorating system is provided with self-adherent, pre-cut decorative appliques that removably attach onto substrate sheets adhered to walls. Both the appliques and the substrate sheets utilize a reusable, non-permanent adhesive coating. Such a coating permits rearrangement of the appliques on the substrate sheets and rearrangement of the substrate sheets on the walls, in a peel-off/press-on manner. Each applique provides decorative imagery of a common theme. Additionally, the substrate sheets may include decorative imagery which cooperates with the appliques to create a decorative wall scene. The appliques can also be adhered to surfaces other than the substrate sheets. The decorative scene presented by the wall decorating system is easily changed by repositioning the appliques or by removing appliques of one theme and substituting therefor appliques of a new theme.
