Just one knot in Noro sock yarn does this.
Fraternal socks. No way to get these to match - the stretch of brown and green in the middle of the right one only appears once, and the purples and greys are there way too often. Too bad, because I really loved the browns and greens!
Whatever. My dancer nephew who lives in Montreal and loves the hand knit socks, will be getting these for his annual sock-Christmas gift. (we have an agreement - I knit him socks for Christmas if I receive a personal thank you for the ones given previously. He's 31 years old - I told him he was far too old to have his grandmother forward his thank yous. And we won't even discuss the fact that his mother has never said thank you for anything...)) I got a text for last year's, so he gets these this year. He is one of the few people in the family other than myself that will appreciate the randomness of the stripes.
Heels to come later.
