Stencils are tools used to create designs or letters by allowing paint or ink to pass through cut-out shapes. They are often made from materials like plastic, cardboard, or metal and can be used for various projects, such as art, crafts, or home decor. By placing a stencil on a surface and applying paint, you can easily reproduce the same design multiple times. Using stencils is a fun and creative way to personalize items like t-shirts, walls, or greeting cards. They come in many styles, from simple shapes to intricate patterns, making it easy for anyone to add a unique touch to their work. Whether you're a beginner or an experienced artist, stencils can enhance your projects with minimal effort.
