Cardboard is one of the most easily available and useful materials for creative projects. Almost every home has cardboard boxes from groceries, online shopping, or household items. Instead of throwing them away, cardboard can be reused to make useful, decorative, and fun crafts. Cardboard crafts are low-cost, eco-friendly, and suitable for all age groups. Children, students, hobby crafters, and even adults can enjoy working with cardboard. It helps develop creativity, problem-solving skills, and hand coordination.
