Attaching an I-Cord handle

I knit myself an iPod sock yesterday and added an I-Cord strap so it can hang from my neck. Starting off the I-cord was no problem, I left three live sts in my bind off edge & knit away. Wheeee! Now I have a long cord attached at one end to the “sock” and the other end still on the needles.

My question is… What’s the best way to attach the end with live stitches to the boundoff edge so it’s actually a strap? Everything I’m able to find on the net is how to attach I cord as edging rather than as a strap. Sorry if this is a really dumb question!!

TIA for your help!
