These are the beautiful results we achieved with our assorted natural dyestuff on silk scarves. The second picture has silk samples using (bottom left, clockwise): rose petal, red beet, and tansy/ willow/ elderberries/ red cabbage/ yellow onions/ sumac/ and cranberries.
The gray/ black scarf was dyed with willow leaves and cooper wire. The lines are where the wire was wrapped around the scarf. They are my favorite part.
Word of warning: we may have left these in the baggies of vinegar too long, because there were a few spots where the wire was wrapped, that ate through the scarves and made small holes.
