[Cob] cob mortar/filler

[Henry Raduazo]

Gene:
	Try paper, mud and sand. I have had good luck using shredded paper  
it is free and you can get it almost anywhere, others have used the  
bales of shredded paper sold at hardware stores as blow in  
insulation. The traditional material is cow or horse dung.
	I usually mix the paper with my feet in a cut-in-half 55 gallon  
plastic drum, but you can also use paint mixing paddle and a 1/4 inch  
drill or a drywall mixing paddle and a 1/2 inch drill in a smaller  
bucket.
