Using self-striping yarn always reminds me of how I adored yarn that changed color when I was about eight. I hope I never totally grow up if it means I have to get too sophisticated for this kind of yarn. One of its advantages is that just plain knitting can be rather interesting but not require much attention. I often knit my socks during Scrabble games when I'm waiting for my turn. (How much knitting I get done depends on who I'm playing with but it does keep me from going nuts during slow games. )
I was also pleasantly surprised by this Zino by Plymouth Yarn in colorway 2. On the ball band the tiny picture can't show the lovely subtlety of the colors. So far it's not looking nearly as stripey as I expected. By the way, the photo shows the sock and yarn in a stainless steel bowl. I like to use a bowl to keep the ball from rolling around on the floor. During the dry season in Monteverde things can get quite dusty.
