The name I gave this project on Ravelry is Scrappy Log Cabin. I also joined the Ravelry group Log Cabin Fever, where others addicted to similar projects can meet to discuss how badly our hands hurt. ;)
Here's an in-progress pic as of my putting down the knitting this evening.
Not too difficult, I really like the way it is turning out, and of course, the farther out I get the more yarn it takes, which means my scraps probably won't be enough and I might actually have to buy more yarn in order to finish it, unless I start using novelty yarn as well as just the acrylic worsted remnants I'm currently using. Gee, what a shame, having to buy more yarn... too bad. :P
