Hi Beldaraan, heres the instructions for darts as its printed in the book:
Measure the length of pieces with horizontal darts at the side seam, not over the area of the dart shaping. To work a horizontal dart, use the following steps :
Multiply the dart depth (usually one or two inches) by the row gauge to find the number of rows in the dart.
Dart shaping is worked on every other row (a right dart is worked at the end of right side rows and a left dart at the end of wrong side rows). Divide the number of rows by two to find the number of decreases on each side.
Find the number of stitches in the dart by multiplying the dart width by the stitch gauge.
Divide the stitches by half the number of rows to find the number of stitches to leave unworked on each side of the row.
Once all the stitches are left unworked , work across the whole piece, hiding the short row wraps
My darts were 2 inches deep and 5 inches long. That worked out at 12 rows / 24 stitches. 4 sts short row each side, 6 decreases in all each side.
The book that I got these from is called ' Vogue Knitting the Ultimate Knitting Book' Its on the pattern forum on this site. I hope this has been of help. Let me know if you need anymore info. If I dont get a reply about finishing the neck , I think I'll have a go at crochet round it :?
