I love the look of this hat – lovely cabling. It’s from a book I found at the library, Aran Knits by Martin Storey. One ball of Brava SHOULD be enough to finish it – theoretically. However as you can see I am close to the end of the Dove Heather Brava Worsted and haven’t even started to decrease for the crown yet. It’s going to be a loose fit, I think, and I could have used thinner needles, but I’d rather order another ball than frog it.
