Humanity is split is a vast spectrum of difference which are highlighted every day is various ways. It is our culture which defines us as who we are. Each culture has its own norms and rituals and aesthetic. The most beautiful way different cultures are brought forth and expressed in their art. Every country, region and era has its own defining point that can be recognized and that represent the history and the sort of its people.
Taking rugs for example. This is one of the most common medium that has been seen around the world. When we talk about different area rugs have their own personal techniques. From how they are woven to the colors that are used to the patters we see on them. Every are has its unique take on them which is definitive of the past and the present of that area. Be it southwestern, Arabic, Turkish, Pakistani, native American, or Egyptian. Each one holds the burden of representing its people. Each one unique and beautiful in their own way.
One cannot be given preference over another, the choice is in the aesthetic of the individual looking to get their hands on one. So when you go rug shopping, you need to do your homework on what you want because there are a lot of options and directions out there that you could go in. what matters is what speaks to you and what attracts you. you could go with something that reminds you of home or a place you once visited or simply just a a pattern you happen to like. But you need to keep in mind that whatever you get has history that it carries with it, centuries worth of evolution of technique and aesthetic went into what you are going to get.
