Traditional style rugs usually have significant borders along all sides.  The overwhelming majority of them have multiple borders within which vine, scroll, flower, and age-old geometric tribal patterns may be found.  They usually have distinct designs depending upon the region and tribe their patterns have traditionally originated from.  In the past these rugs were generally classified by the people living in the areas of rug production as fine (city) rugs and rustic (village) rugs.  The designs of the 'village' rugs were generally more blocky and straighter lined whereas the 'city' rugs' were more refined and curvy.  Further classifying the design of the rugs, they were assigned to the originating region as Anatolian, Kavkaz, Persian, Sino-Persian, Moghul, etc.   Finally their design was then classified more specifically by city or tribe of origin, some examples being Tabriz, Herati, Bakshaish, Jaipur, Gabbeh, and Ersari.  Nowadays, while these rug styles and designs are still made in some of the original areas, unfortunately there are not many true nomadic tribal rugs being made due to the near extinction of this unique type of lifestyle.  Modern technology has allowed for the quick and mass production of machine-made rugs thus allowing all styles and new unique design combinations to be produced all over the globe.
