Yes, the green and purple ones. My sister uses the circular needle technique and recommends it; maybe I'll try that out for the next set I make.

I also really like the ribbed/cabled border on the sampler blanket (which is why I took a closeup of that) and think it might be cool to use for socks, although that might require a little experimentation to get right. I guess it's something to think about for the future, anyway.
