Here is a link to an I-cord bind-off:

Scroll down just less than half-way down the page and see the section entitled "I-Cord Bind Off".
I began my I-Cord Bind Off with 3 stitches of the Knitted Cast On, and although while following the instructions, the process seemed very strange and convoluted, it resulted in a very nice finish to my I-Cord.
