Kool-Aid works amazingly well as a dye for yarn or
roving.  We like to use it to dye roving for needle
felting projects.  What amazes me is that once the
dye sets, the colors do not bleed.  Here is the procedure.

Use 3 parts water to 1 part of vinegar.  For lighter colors,
use less kool-aid.  For brighter, richer colors, use more packages of kool-aid.  You will really need to experiment
with the colors to get the shade you desire.

1)  Soak fiber in hot water for 30 minutes.
2)  Mix up your dye solution and heat to just below boiling.
3)  Remove the fiber from the hot water soak and squeeze
out excess water.
4)  Completely submerge the fiber in the dye bath.  Add
more water to completely cover, if necessary.
5)  Simmer for about 45 minutes or until all the color is
gone from the water.  During this time, carefully turn the
fiber periodically to ensure color is even.  When liquid becomes clear or in some cases, a milky white, turn off
heat.
6)  Let cool until you can handle fiber.
7)  Rinse fiber in water the same temperature as the
dye bath. 
8)  Hang to dry.

Winter Weather Tips

*  Increase feed intake
*  Use heated water buckets
(alpacas often won't drink very cold water)
*  Put hay on barn floors to help keep floor
area warm
*  Keep the alpacas in during icy weather -
so they don't flip and fall on the ice.  Consider
removing the ice in their paddock area with a tractor
*  Be aware of wind direction in order to maintain
minimal air flow through the barn

*  Watch your alpaca's behavior. 
You know what is normal behavior for your herd. 
Pay close attention to any behavior out of the ordinary.
