I have several silk scarves that I have been intending to overdye, and of course black is a good choice for such an endeavor. This one had previously been pole-wrapped and I decided to use the same technique once again. I like the results. I used double strength of Pro Chem's 'Silk Black' (#610). Here are a few more shots of that scarf:
In the same bath, I also pole-wrapped and overdyed a green/yellow/blue number that had previously been dyed with acid dyes, alcohol and some salt. I think you will agree that the results are rather interesting.
I took these photos with my iPhone, so the quality isn't as good as it could have been had I used a better camera and more light (we are in the midst of yet another thunderstorm right now!). The black in the last two pics is actually deeper than it appears here.
