The picture shouldn't ever show decreases every 4 rows instead of every other row. It does. Click on it and make it big and you'll see (it's especially obvious on the sleeve side of the raglan seam)
I may just start adding rows in there because quite frankly, it needs them and there's no way that there will magically be 15" at the start of the neck and hood. The back, which is the longest point of the sweater, is currently 9" long. I have 16 rows of decreasing left. At a gauge of 25 rounds/4 inches, I'll be lucky if this thing is a 12" total. gah. If I turn 16 rows into 32 rows, then I'll get (quick math) 5 3/4"... Oh hey. 9"+6" makes 15". But did I mention that I already added 2" on to this thing? Yeah.
I am so angry right now. Patterns need to be test knit before you publish them. Someone needs to be paid to catch this sort of thing.
I would post pictures, but it's not particularly interesting to look at right now because I've got it crammed onto a small circular needle. I decided to compensate for the difference between my rib cage and my bust line by shrinking down the cabled hem. Now I have 36" worth of stitches at the bust and 34" of cable under it, which means it shouldn't flare out unpleasantly. I knit 1" before starting the pattern. I also waited to add on the sleeves until almost all of the short rows were completed. That works out to an extra 2" of length. I'll probably make it to the neck soon--it's smooth sailing in the knitting department. I just have to stop and reevaluate every few rows to make sure something new and exciting hasn't gone wrong.
I have a diagram drawn for the hood, and as soon as I know how many stitches I have (aka, when I get there), I'll write a recipe.
