Hi Nat
I think you should tell the seller, if it had black hairs in it it should
have been advertised as such.
Have you tried Heather at Braeside alpacas,
http://www.braesidealpacas.com.au/ if you contact Heather and ask her I am
sure she will help you out.
The other place that I did get beautiful alpaca from a few years ago was
Petlins in Sydney http://www.petlins.com/, Lindy is also really great and
if you ring her will help you out!
Good luck with it!
Sandie :-)
