This cowl is super soft - especially if you use Bernat Roving as I did. But any chucky wool (5) weight will do! It’s always fun to experiment and see what different wools with different textures will do for the same pattern. I love the unique textures of the braids that gives this cowl depth and difference. I also love the buttons that ‘look’ like you’ve just secured the braids yourself. You can, of course, work the cowl that way, but then you’d be constantly re-braiding it! Using the chunky wool and doing single crochets between the v-stitches causes the v’s to ‘pop’ out of the cowl in square sections. It’s a really neat and different look. I hope you love this cowl as much as I do!
