How do I add an I cord as the top of a bag?

[Binkyman99]

I have been making the booga bag version of bags and have enlarged the pattern for a larger tote type bag etc. A friend has told me that I should add an I cord on the top of the totes to give them a more finished look. She said it can be knitted on. She would show me, but cannot do so for a few days! I really want to finish this thing.

So if you know what I am talking about and can help or give me a link to a place that could I would appreciate it!

I know how to do the I cord with dp needles, but it sounded like this was something I could do before casting off?

This sounds like what you want to do.
