I have already had several comments from folks who would like to see this design in a cardigan version. I don't have any immediate plans to do that, but I am happy to share a few instructions on how you can accomplish this modification! It is really nothing fancy. It will be easiest to follow along with the Jesse's Girl pattern while reading these notes, but the principles are definitely applicable to other designs as well.
First, adjust the cast-on to remove width for the buttonband. For this design, I suggest you CO 6 fewer stitches. This removes the center front cable only while providing for 2 selvedge stitches (one at each edge). The selvedge stitches make it easy to pick up for your buttonband. In this design, it is important to set up the Ribbing properly, so that your side Ribbing matches with the hem. With this in mind, set-up your Ribbing like this:
Row 1 (WS): P1, k1, *p2, k2; rep from * to last 4 sts, p2, k1, p1.
Row 2 (RS): K1, p1, *k2, p2; rep from * to last 4 sts, k2, p1, k1.
After you work the hem, and this is the only tricky part, map out your cable set-up row since the end-of-round for the pullover is not in the center front. The easiest way to do this is to draw yourself a little picture like so:
