Weld 400% wog

Weld (2nd dyebath)
Alum, No after-treatments

I've since learned that I get better color if I use my tap water (I have hard water) and let the weld boil while preparing the bath. I treated it much too gently in these samples, and got a very dull color. 100% wog is plenty, and the fiber only needs 5-10 minutes in the dye bath for eye-popping color. A re-dye is definitely in order here.
