Tartan is associated with the Scottish heritage.
The pattern itself consists of stripes with different widths and colors which cross each other in 90° angle, this way they create a grid pattern in both directions which has a checked pattern effect. There are same stripes in width and color on both sides of the main stripe in vertically and horizontally also, so the pattern is completely symmetrical. This differentiates tartan from other similar checked patterns. The order of the threads is reversed mixing the two colors with this and „creating” a third one.
On the contrary to the popular belief, in old times rather institutes, regions and families had the same clothes, not the clans. The pattern was connected later to the Scottish nationality and costume. First it was only used on textiles for clothing, these were made of almost only wool and were colored with natural dyes. Artificial dyes became widespread in the Victorian era allowing new color variations to be used.
Nowadays tartan isn’t limited only to clothes, or to the fabrics at all. It appears on objects made of any material, be it paper, porcelain or plastic. Because of this fact, there are many possibilities for using the pattern in interior design: not only on upholsteries but on wallpaper, lampshade, dinner set, carpet etc. The variations of it with red-green color combinations are associated with Christmas mood.
