This sweater is from the author of a book called Crochet that Fits. I got the pattern from Knit and Crochet Now (Season 3; requires login), so I haven't read the book, but if the other patterns in it are like this one, I will probably try to find a copy.
Here's why: this sweater involves unconventional construction, and from what I can tell, it appears it will offer a better fit and drape than a traditionally designed crochet sweater. It is worked in vertical rows rather than horizontal ones, and shaping is created by changing stitches rather than by using increases or decreases. I won't know until it is finished, but this style of construction is promising, and I hope to incorporate basic concepts from it into my own future designs. I'm intrigued.
It has taken me about 2 weeks to finish the front piece and about half of the back. I've had more time to crochet than usual, so it may not be accurate, but that makes it pretty quick for a sweater.
My gauge is significantly different from that of the pattern, so I added 10 rows to match the necessary width, and with a starting chain of 86, my sweater is a little bit longer than the one in the pattern.
Here is a detail of the band on the front. It is simply 8 sc and 1 hdc. It appears to be an effective means of creating a fitted empire waist, but I will have to piece it before I know for sure.
More to follow as I progress...
