I enjoyed making it, I used 4" DPNs (size 0000, tiny!) which worked. 6" might have been a little easier in the first row or two, but I don't think it would've been significantly easier.
Now that the scarf I wove is off to its recipient, here's a picture of it when I started taking it off the loom. (or it started taking itself off, either way. at least i was finished at that point. :)
