Since 2005 Yuke Setiyoko Simon, the owner and designer of Lenan - Pearl of Silk, has been purchasing Attacus and Criculla cocoons from people who gather them. Attacus Atlas silkworks breed on mahogany trees and produce exotic brown colored wild silk. The Cricullatriphenestrata silkworms breed on cashew trees and produce a gold-colored wild silk. This wild silk is unique to Indonesia. Simon processes these coccoons into wild silk thread. This wild silk thread is then woven into various products, such as scarves, wall hangings, Japanese obi, sarongs, and material for shirts. In the finishing process, the wild silk "tenun" (woven cloth) products can be left natural, further colored, or occasionally given a hand-batik painting.
Lenan - Pearl of Silk, for the past few years has been developing exclusive tenun products, utilizing this special wild silk processed from the cocoon of mahogany and cashew leaf -- eating silkworms. As the name of the silkworms suggest, Attacus products are made from the brown wild silk and Criculla products from the gold wild silk.
Simon's wild silk products have been showcased at various exhibitions in Indonesia and abroad. International exhibitions include Tokyo in 2005, Niort, France, in 2006, the Asean Centre in Tokyo in January 2008 and Brussels, Belgium in May 2008.
