I am looking for 100% Alpaca sweaters that are made by Hallett, from
San Francisco.  Any idea if they have a website?

Hello and thanks for your question.

The website for Hallet Handknits can be found at:
http://www.alpacawoolsweaters.com

I believe this is the company you are looking for since the name is
almost identical to the one you mentioned and they specialize in
importing hand-knit alpaca sweaters.  They are also located in the San
Francisco area.

To find the retailer nearest you that sells Hallet Handknits you can
call toll-free:

You can also email them at mhallet@aol.com
