Today we're turning the stripes on their side! While horizontal stripes are the norm for self-patterning sock yarn, getting a vertical look is a little trickier.
For knitting, I'm recommending Stripe Tease, a sock with very unusual construction. The narrow strips make each section of yarn form a longer patch, and the effect in self-patterning yarn is a fun patchwork. Look at the project pages for inspiration (though if you're in love with the gradient you see on the main pattern page, we do also carry Zauberball).
For crochet, this is not a traditional pattern, but rather a recipe for custom-fit socks! Short-Faux Heel Socks mimic the look of a knit short-row heel, but the direction of work forms attractive, vertical stripes. This is a great opportunity for one to explore what makes a well-fitting sock.
