If you're thinking of moving to New Caledonia for a few months or a few years, "Leave your silk and wool behind!" advises the local dry cleaner.
New Caledonia is so humid that in a short time your leather will show signs of mildew and later mould. Your silk will turn yellow (never to be repaired) and your wool will either sprout funny little holes and/or smell bad for the rest of its life.
We live and learn!
