I thought about all the other construction methods I knew for top-down knitting and I tried to combine all of the parts I liked about them... and I before I knew it I got a yoke that was something like a mesh up of contiguous, raglan, saddle and set-in sleeve... all in one!
This sounds actually quite horrible, but I was very pleased with the "combination" yoke construction that I finally ended up with!
... I almost gave up on it, but I got so many lovely comments on my project page on ravelry that encouraged me to give it another try!
The pattern I ended up with was quite advanced naturally - so I wrote a completely different yoke construction (this time a saddled raglan yoke) for a separate version of the same cardigan, so as to make this pattern accessible to intermediate knitters, too.
