I have spun about 1,000 yards of yarn and I have my Spire on my needles. I am a little further along than the picture above. The color is blending very nicely and I am very pleased with it. I am still working out in my head how I'm going to do the blending for the knitted on edging so I'm keeping 8 oz of roving unspun so I can work on those details as I go.
In the mean time I am loving the ease of this pattern and I'm enjoying how quickly it is knitting up, but like all things that start from the center I'm sure progress will start slowing soon.
