  • Patent number: 6159582
    Abstract: Decorative patterns for use on Venetian blind and wall paper, including a paper substrate layer, a stripe sandwiched layer and a paper face layer. A paper pulp is first laid into the paper substrate layer with a certain thickness. Then dry flowers or decorative papers are evenly sprayed over the paper substrate layer to form the stripe sandwiched layer which has high and low levels. Then a thinner paper pulp is laid over the stripe sandwiched layer to form the paper face layer. The paper face layer only covers the lower portions of the dry flowers or decorative papers of the stripe sandwiched layer so as to clamp the dry flowers or decorative papers. After dried, planed and pressed, a flexible cover article with solid structure and natural versatile solid pictures on one face is achieved.
