I have now finished two solo socks:
I’m about 3/4 of the way through the second blue sock now, and will start the other rainbow sock as soon as I finish that one. Since I don’t expect to have a whole lot of time left in my trip (I fly home tomorrow), I expect it will be a total of three pairs of socks for the trip.
I think in the future I will stick with solid colored yarns or else use the multicolors as in the rainbow sock. With multicolor yarns, the pattern really doesn’t show up as clearly as I’d like, being dominated by the color changes (esp. at a distance).
Regardless, they’re neat socks. I like ’em.
