cabling around corners

[ladysaphira]

Background: I'm just beginning contemplating designing a cabled fitted vest.  I'd love to have a cable that runs along the bottom.  I figure I'll need to knit the cable first and then pick up from along the side to knit the body.  Now here's the tricky part - I'd love to take that same cable and turn the corner and have it run up the front edges of a cardigan-type vest.  But how to turn the corner with the cable?  The only idea I have so far is to modify the technique used in Jeanie or to try a mitered cable corner something like this.

My question is can anyone point me to any other techniques for cables turning corners?
