You bound off 14sts on opposite sides for the armholes? I don't know your gauge but it kinds sounds like a lot to bind off for the underarm.
Anyhow,once you've bound the sts off, don't try to cross over the bound off sts. Just work back and forth on the section that has the yarn attached (if that's the way you're going to make the front and back). Leave the other stitches on a stitch holder or some scrap yarn until you finish the back. Then you can work the front.
