I don’t know how to grade patterns. But many have requested one. So...
This is given as a recipe. Choose your yarn (I suggest a bulky cotton) and needles. Swatch. And just follow the recipe for a perfect fitting cool lacey summer top.
This top is also knit using the contiguous style for the sleeve cap/armhole shaping. It is knit as all one piece after you finish the neckline. for more info on contiguous check [this blog] post or the [ravelry group.]
also if you need more details on making the boatneck, see [this post.]
This sweater does require an experienced top down sweater knitter. Or at least someone comfortable with lace and decision making!
