Peruvian Highland Wool?

[deliciouspear]

Does anyone use Knitpicks "Wool of the Andes" or "Shamrock" yarn?

They are both made with Peruvian Highland Wool - which I can't find in my local yarn shop to feel on.

I'm always curious to try it but I have a nearly insurmountable THING about buying yarn online that I haven't touched before.

Can anyone compare it softness and/or sturdiness wise to any of the following?

Purewool 3-ply
Gaia
Peace Fleece
Hippy Dippy Worsted
Lamb's Pride

Would you use it for something next to a baby's skin or the skin of a super-sensitive adult?

Thanks!
