Decoupage is a craft technique that involves decorating an object by gluing colored paper cutouts onto it. This can include images from magazines, wrapping paper, or specially designed decoupage papers. After applying the cutouts, a sealant or varnish is often added to protect the surface and give it a finished look. The process can be used on various surfaces, such as wood, glass, or metal, making it a versatile art form. Decoupage is popular for personalizing items like furniture, boxes, and home decor, allowing individuals to express their creativity and style.
