Closing in on the Hem

After a few evenings of concentrated knitting, I am finally approaching the hem of my Briar Rose Glory Days cardigan.

Right now, the body measures close to 10". I think I want the total body length to be about 13", but I'll have to check a sweater that has a similar fit to be sure. In any case, I need to decide if there will be a bit a regular rib (k3, p1) at the end and whether or not I'll go ahead with an I-cord bind-off.
A nip of a strong beverage may help me decide.
