Eight-Yarn Never-Ending Spiral Granny Square

:: another break from owls; more crochet :: 

The question at the end of my Never-Ending Spiral Granny Square post wouldn't leave me alone. And now I know -- it CAN be done with eight yarns. In fact, after the initial mess of the first few rows, it's even easier than using four yarns.

I think it would look great with 4 strands of white and 4 strands of various colors. Or 8 yarns in rainbowy hues. Or actually anything would look better than the "antique lime" and "harvest gold" and "pumpkin" used below. But it's what I had in my scraps.

Looking at the picture again now, I'm already seeing things I want to change. Specifically, the beginning and the ending. I see more spiral crochet in my future. But, ugh, I must find some new scrap yarn for these test squares!
