just to be sure, your border is for the neck, right?
Or is it for the hem? Or the armhole?
Or all 3?
Judging from your pattern, you're starting from the hem, working your way up to the neck.
If that's the case, you need to work as they say MINUS 2 inches, and then come and pick up your stitches for the border. It sounds like you want a wide border, so maybe you could try with K1 P2 for the first inch, and then decrease in your purl sts to end up with k1 P1? But have you planned to have a border in the back as well?
Hope this helps
