The simplicity of life enjoyed by the weavers is reflected in the style of their production.In spite of the patterns,which are not ordered and regular,the designs are still attractive and pleasant.
The designers have transferred these patterns from one district to another so that these designs can be found from the furthest east to the furthest west of the country.
Sometimes these designs are recognised by the name of the production zone such as Mazlaghan,Ferdous,veis,and may take the name of the chieftain such as Salar-Khani,Yaghub khani,Ali-Mirzai.
