Best way to attach I-cord?

[Antares]

I am trying to create straps (using I-cord) for a top, and I'm wondering what is the best way to do this.

Should I completely bind off the last row, and then pick up stitches and work the I-cord. Or should I work the I-cord first and attach it after it's complete?

Any suggestions?

*This is what I would do (pick up on the front). It will secure your CO row so you only have to attach the I-cord BO end when done (to the back).

Or should I work the I-cord first and attach it after it's complete?
*Then you have to attach both ends.
