The sari as cloth:

Saris are woven with one plain end (the end that is concealed inside the wrap), two long decorative borders running the length of the sari, and a one to three foot section at the other end which continues and elaborates the length-wise decoration. This end is called the pallu; it is the part thrown over the shoulder in the Nivi style of draping.In past times, saris were woven of silk or cotton. The rich could afford finely-woven, diaphanous silk saris that, according to folklore, could be passed through a finger ring. The poor wore coarsely woven cotton saris. All saris were handwoven and represented a considerable investment of time or money.Simple hand-woven villagers' saris are often decorated with checks or stripes woven into the cloth. Inexpensive saris were also decorated with block printing using carved wooden blocks and vegetable dyes, or tie-dyeing, known in India as bhandani work.More expensive saris had elaborate geometric, floral, or figurative ornaments or brocades created on the loom, as part of the fabric. Sometimes warp and weft threads were tie-dyed and then woven, creating ikat patterns. Sometimes threads of different colors were woven into the base fabric in patterns; an ornamented border, an elaborate pallu, and often, small repeated accents in the cloth itself. These accents are called buttis or bhutties (spellings vary). For fancy saris, these patterns could be woven with gold or silver thread, which is called zari work.Sometimes the saris were further decorated, after weaving, with various sorts of embroidery. Resham work is embroidery done with colored silk thread. Zardozi embroidery uses gold and silver thread and sometimes pearls and precious stones. Cheap modern versions of zardozi use synthetic metallic thread and imitation stones, such as fake pearls and Swarovski crystals.In modern times, saris are increasingly woven on mechanical looms and made of artificial fibers, such as polyester, nylon, or rayon, which do not require starching or ironing. They are printed by machine, or woven in simple patterns made with floats across the back of the sari. This can create an elaborate appearance on the front, while looking ugly on the back. The punchra work is imitated with inexpensive machine-made tassel trim.
