I am to use this crochet pattern but use the color sequence of the knit version.
October 10... It has gone quite fast. I have enough yarn for one repeat each of blue and red, I think. Hope to finish it during the coming week.
October 13… Done.
I did many modifications, like using a larger hook, different color sequence and slightly different way of doing the ribbing. I started with black yarn instead of red, so the ribbing ends at the edge of that central black circle and there is no bunching at the center.
