So an update on the Osgood scarf - I'm progressing through it, though its probably only about 10% done. It's looking very nice so far, I've been pleased with how enjoyable it is to knit the ribbing. The white/clay sections are the most annoying by far. I've come to decide that is because I enjoy knitting the colors much more.
For those of you working on a scarf of your own, StarCATs over at Ravelry has done an insanely excellent job of compiling the data we know and making the observations on the row counts, fringe, and edges of the scarf. If you're interested, I would recommend going over to Rav and checking out her project page which has a graphic with the row counts that is very useful.
I've mainly been working on it when my hands hurt too much to crochet toys at the tight gauge they need to be at, so I don't think its doing bad for working on it here and there.
