A one-piece backing and support element comprises a flat backing panel (12) and a support leg (15) cut out form the backing panel (12). At least one stay (16) is also cut out form the backing panel (12). Each stay (16) is integrally connected, at its lower end, to the backing panel (12) and at its upper end to the support leg (15). The upper end of the support leg (15) is releasably attachable with a detent (14) on the backing panel (12) to retain the support leg (15) and stays (16) in erected positions in which they extend at an angle away from the backing panel (12). |
