The next time you shop for a yoga mat or for a floor covering when your tiny tot starts to crawl on the ground, why not buy a &lsquothazapaya&rsquo This plant-based eco-friendly mat is one of Kerala&rsquos oldest handicrafts. Made from screw pine or pandanus palm &ndash known as Kaitha or Thaza in Malayalam and Kewda in Hindi &ndash the shrubs were once found in abundance across the state, growing along the banks of rivers and lakes. Traditionally, the screw pine had many uses &ndash as barriers along the edges of fields and canals, as checks against soil erosion, etc. It was also found that the leaves of the plants could be woven to produce mats that felt cool in summer.
