I just winged it. I'm actually not happy with the design so I am planning to rip it out and knit Ann Norling's 'Easy Cowl in Any Gauge' pattern #71. I want a long cowl that looks good looped over and I'm just not thrilled with how this one turned out. I LOVE the Ann Norling pattern and it would look great in this gorgeous Malabrigo Twist Yarn. This yarn is so soft and squishy, and amazing to knit with! I used 2 skeins on a size 10.5 needle (I used Plymouth Bamboo Circulars, 32'. They have amazingly sharp tips!) I think I'll do the Ann Norling pattern on a 9 or 10 though. This yarn will look nicer at a slightly smaller gauge.
