It's been a while for this foursome design! Had the yarn since November but had a tough time with my swatching work. I think the wait was worth it though. I used 2 skeins of Sandrasingh yarn (blue variegated)
to create both the hood scarf and the cowl. I used 3 skeins of the Malabrigo yarn (lettuce green) to create both the hood scarf and the cowl and probably have just enough yarn to make 1 more cowl.
I'm really happy with the outcome - and depending on your style buttons-no buttons, short scarf-long scarf,
2 skeins-3 skeins, I think this patten will accommodate your style.
