Step-by-step explanation:
The pattern of overlaid diamonds that gets its design from the Scottish tartan of Clan Campbell is commonly known as Argyle. This pattern is synonymous with traditional Scottish attire and has become popular worldwide, especially in knitwear such as socks and sweaters.
The origin of Argyle is deeply rooted in history, particularly in the clothing traditions of Scotland. Scottish tartans represent different clans or families, each with their unique colors and patterns formed by interwoven lines and checks. Clan Campbell's tartan inspired the Argyle pattern, which features a series of diamonds or lozenges, usually overlaid with intersecting diagonal lines. Tartans such as Clan Campbell's were created using locally sourced wool, which was spun, dyed, and woven into a heavy cloth suitable for the cold Scottish climate. This tradition of weaving tartans was passed down through generations, with local weavers customizing the patterns for specific families or communities, thus making each tartan pattern distinctive.
Later, items like blankets began to adopt these intricate designs, incorporating diamonds, zigzags, and stripes, highlighted by the use of vividly colored yarns. These designs have evolved over time and continue to influence fashion and textiles around the world.
