Here is alum soaked cotton yardage - wrapped up with pine bark from the Ponderosa Pine trees that surround my home.
I gathered pine bark and boiled it on the burner of our BBQ grill. This kept the smells outdoors, and it worked great. The dye extract was pretty brownish - kind of a yellow brown.
I boiled the fabric in the dye extract for 5 hours, then set it all aside until the dye water evaporates. It will not be "finished" until sometime this summer. Stay tuned!
