This cowl is knitted in one-piece, using both circular (for the neck piece) and two needles for the leaves. I used Debbie Bliss Blue Faced Leicester Aran, but other Aran (10ply) wools would work well. It takes approximately 140g of wool, so you would need 3 balls of the wool I have used. The neck section has a simple cable stitch.
Although similar to my children's version, the neck section is deeper, and the leaves larger, meaning the finished width of the cowl is bigger, to suit an adult's shoulders.
The cowl pulls on very easily, and is very cosy. It fits warmly round the neck, and is very stylish. You could add a bead on the tip of each leaf.
