BSJ I-cord border

HI, I'm just finishing my first BSJ. I'm trying to figure out how to pick up stitches around the cuff for an I-cord border. I get how to attach I-cord to live stitches, but can't seem to figure out how to pick up on a cast on edge. Help! Please?

Another Baby Surprise!

Here is my most recent Zimmermann project.

This one is made with some lovely Berocco alpaca. It is so soft. I love this pattern.
