I've finished knitting the first of two hanks I dyed a few weeks back. I did a total of four, two at a time. The first two the color was even and a richer brown. The two I'm using for the Hiking Scarf dyed unevenly and had some green hues. The true color is a khaki (is it British khaki that is greenish in color).
Anyway I looked for a project that would forgive some of the color variation and I think I found it in the Irish Hiking Scarf. I actually really like this project because of the color variation. The color gives it more of a rustic look I think. Anyway, here is a picture of half of the scarf. You can see the color variation pretty well in it. In real life it's also pretty subtle but noticeable.
