Final answer:
A piece of cloth that has a design and is used by countries is a flag, which reflects a long tradition of significant and symbolic textile use across different cultures and history.
Step-by-step explanation:
A piece of cloth that carries a design and is used by countries is known as a flag. This definition aligns with the various historical and cultural contexts in which cloth has been used. For instance, quilting has evolved from simple stiched-together fabric scraps for practical use to a form of artistic expression deeply influenced by modern art movements. Historical examples such as the quilted tops worn under armor during the Crusades to whole-cloth quilts of the 18th century indicate the diverse applications and importance of quilting. Similarly, in certain African cultures, wax-print fabrics serve as a method of nonverbal communication with specific patterns symbolic of proverbs, occasions, and notable individuals, reflecting a rich heritage of textile design.
