Design a chic window decoration using stenciling techniques for CNY. Create a large stencil of a snake intertwined with floral patterns, and apply it to the window using red and gold spray paint. The transparency of the window allows light to filter through, creating a striking visual effect. Incorporate elegant calligraphy with a festive greeting at the bottom of the design. This artistic and interactive decoration will add a festive touch to any home or business during the Year of the Snake.
