Abstract: A pre-fabricated decorative moulding system which can be temporary, semi permanent or permanent, requiring no tools other than a tape measure or rule and a pencil or pen to install. An embodiment could be made of wood, plastic, or any material suitable for moulding, wainscot or appliqués. The system includes one or more devices, typically square or rectangular in shape. A device may also be of other shapes, angles or curves. A device would include a pre-applied double sided adhesive tape attached to the backside of the device with the removable adhesive side exposed which is capable of adhering the device to a surface and later easily removed without damage. The device can then be adhered to another desired surface.
