I read about buying cashmere at moreintelligentlife.com and this got me thinking about all the different types of wools and I ended up at this very informative page at STP: Guide To Wool
Alpaca sounds amazing though it is well-known that I have had a long time love affair with merino.
And it is also good to remember that cheap cashmere has a high cost that someone else has to pay for.
