Have you had this problem before? Really loose purl stitches coming right off a column of stockinette in your ribbing? This is the reason why this pair of socks languished in my abandoned WIP pile since Christmas last year ... I know I've made ribbed socks before without a problem, so I'm still a little perplexed about this. Any tips? Since I was frustrated, this sock was frogged. In the meantime, I cast on and completed a new, plain vanilla sock using the remainder of the skein. See that ball of yarn on the right below? That's the original frogged sock! So now I know, I can officially finish three single socks from one skein of String Theory Colorworks Continuum sock yarn, which is good to know. This is the Lanatum colorway, which reminds me of watermelons. And spring!
