Below is Schaefer Yarn Lola (ie sport weight) in an insane colorway called Frank's Folly. My camera can't deal with it; it's a slightly richer and less electric red in real life, but still pretty insanely bright.
Last is Claudia Handpainted (Sportweight) in Santa Fe, with Lorna's Laces Shepard Sport in Harvest for contrast. I was trying to get a picture that showed how the LL matched one of the colors in the CHP, but ended up with both either looking washed out or all yellowy; you can, however, see that they match! The LL looks heavier but if I'm using it for heels and toes I suppose that's a good thing.
I'm looking forward to trying sport weight socks; now I'm gonna go see how far I can get on that Crazy sock in what's left of my weekend!
