I don't think it would work. Alpaca doesn't have enough body to it for the finished item to hold its shape. You'd be washing your soaker pretty often to re-shape it.<br><br>
You'd be better off making it a scarf or something.<br><br>
You <i>could</i> dye it with Kool-Aid, though.
I don't know about Alpaca, but mohair does work, as does angora (that would be goat and rabbit) I have some beautiful wool/mohair blend, yes you can koolaid dye any kind of natural fiber (including the stuff that grows out of your own head <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/wink1.gif" style="border:0px solid;" title="wink1">) Anyway the mohair and angora don't have a problem holding shape, maybe if you made a soaker with wool/Alpaca blend? good luck! ~
