Natural black weaving

I wasn't particularly pleased with my black after the skein had completely dyed.  But I carried on and tried to look past it because it was just test for experimenting. I made a few little card windings and honestly I think I should have spent a little more time on them. I only made 2 windings, with the idea that I wanted a mixture of black on one side and white on the other. But I wanted the colours to blend in together in the middle and the blend out to soild colours of black and white. Already unimpressed by the black, I returned to my dobby loom and began to set up with this new warp. I kept the length of my warp under 2 metres as I didn't want to spend or waste too much of my time or the yarn.
