Beads are small objects of different shapes and colors, perforated in the center, primarily used in jewelry creation, decorations, and other crafting projects. They are made from various materials such as glass, ceramic, wood, plastic, or metal and can have different finishes and textures. Beads can be used alone or in combination with other beads or materials to create unique patterns and designs. They are often attached to strings, necklaces, or nylon threads to form necklaces, bracelets, earrings, and other jewelry, but they can also be incorporated into other crafting projects such as decorations, embroidery, or artwork.
