I have applied one more wash to the ties, this time brown with some yellow mixed in. The purpose being to kill the somewhat greenish effect of the dry and diluted India Ink, and also to simply create an overall color variation. Once again, I used nothing fancy but what I had at hand - light brown hobby acrylics and yellow from a children's watercolor set, mixed in plain tap water. Here what it looks when just applied.
And when having dried. On purpose, the effect is quite subtle.
