Silken Magic - Thai silk is renowned for its quality and beauty, but most of its wearers know little of the process that creates this coveted fabric. Silkworms spin their cocoons in one continuous thread, more than a mile long. the cocoons are boiled to kill the worms without damaging the threads, and in a seemingly magical process, dozens of individual cocoon threads are spun from the boiling cauldron into a single thread of silk.
