Well - my fears were realized. I have 1/2 a sleeve left and I'm nearly completely out of yarn. I managed to find a place that had the right color but not the lot and after 6 mos I'm pretty sure no one does have the right lot, I know that the store where I bought the yarn doesn't have anymore. I bought a skein anyway and I'm going to hope for the best. There really isn't any other choice. If I'm creative and careful only the back of one sleeve will be out of the odd lot.
With any luck at all the lots won't be too different and they will only butt up against each other on one sleeve seam.
This is the second time I have followed the yardage recommendations on the pattern, bought extra and still run out. And it isn't just a little bit off, it's over 100 yards off, a whole 1/2 a sleeve off. I might have enough of the CC to finish the neck band, maybe, but even that might be wishful thinking. It is very frustrating. Although considering the amount of knitting I do only 2 isn't so bad.
I'm still so disappointed.
The yarn for my husband's sweater should be here today.
