Over, under, in between… The extra layer to keep you warm or the sleeveless tank that lets you shed your jacket. Our Ribline Vest is a clothing chameleon, exactly what you need it to be as you navigate the day!

You start this one at the bottom, making a flattering split hem by casting on the front and the back separately. You work a tidy half-twisted rib, whose beautiful lines trace up the sides as you join to knit the body in the round.

After dividing again at the sleeves, you shape the front, then the back, and finally, rejoin to knit the collar in the round.

With its distinctive high twist, our 100% extra fine merino Plenty is a wonderful yarn for this crisp, stylish knit.

Plenty is ridiculously soft, so it’s a perfect choice if you’re wearing this vest on its own, and at the same time, its plump worsted-weight warmth ensures you’ll be cozy if you’re layering!
