Alpaca

Purchased a big bag of this material from an alpaca rancher recently.  It contains all-natural hair fibers (no dyes) in black, brown, beige, white, and gray colors.  Below are four of my jigs tied with the brown alpaca fibers.

This material seems much like wool roving.  The major difference is that alpaca fiber is hollow and water resistant, meaning it would tend to float initially.  Lambswool or wool roving absorbs water rapidly, making jigs fairly heavy.  All of the fibers mentioned move well under water.
