[Cob] Buying bulk wool

[Clint Popetz]

Hi,

	I just finished a cob greenhouse, and need to insulate the
roof.  I'd like to use wool, but as winter is just starting, no one
(around here) is shearing :)  Does anyone have a good resource for
bulk wool?  It doesn't need to be cleaned or carded.  Also, does
anyone have numbers on density, so I can calculate coverage when
buying by the pound?  I seem to remember around 1.5 pounds/ft3, but I
can't remember where I read that.

			Thanks,
