I've thought about getting that pattern. I know that I would have to raise the neckline a bit - I just don't quite do the plunging neckline thing. In a light-weight yarn (she recommends a DK weight) that should be a really nice sweater.
I have purchased the pattern for the Butterfly Wrap from Stitch Diva and hope to make it this summer. The pattern seems to be well written, with several photographs of the stitches and a stitch diagram. The skill level is also Intermediate and it is not a pattern for beginners. (But I really like challenging patterns.)
