It's directly inspired by Jesse's version in the post I linked to, and I'm using the Hue Shift pattern. I'm using up sock yarn scraps, and have also purchased some fun mini skeins from various yarny sources. I swapped some mini skeins with Jesse, and plan to do so with Amanda as well!
I'm starting my eighth square (with a total goal of 144), and I've enjoyed every stitch!
My only complaint is that I have to take breaks from knitting (I fell on some ice in New Mexico last winter, and my right wrist has been intermittently tender). But I guess that's okay, since I have plenty of other projects to work on. I know this will be a long-term WIP, but it is fun and eventually, I'll have a blanket!
