Traditional carpet

Because this Akstafa design is symmetrical, the weavers can complete the remainder of the rug's pattern themselves - though they have to mentally flip and reverse the cartoon to do so. It is an exercise in abstract thinking for everyone involved, and one that dates back to the very earliest days of the settled carpet trade.

But when carpets are non-symmetrical, or contain surprise elements in some parts of the field but not others, the cartoons have to show more. Then designers may draw a half of the rug or even the full rug. And at that point, drawing a carpet can become as time-consuming as any other form of portrait art.
