Silk #1

A young lady in Laos dyeing silk thread. The PiPs show silk cocoons being heated in water and silkworm moths. The silkworms encase themselves in a cocoon of silk thread and, to remove it, the cocoon needs to be heated in water. Long ago, when I was a kid, many of us used to raise silkworms and remove the thread just this way - I suspect few kids do it now that electronic games are here!
