This is my most used knitted item.
I wrote out the directions if anyone is interested.

At cast off the last 3 sts at back start a 3 st icord.
I made the icord 30”
When I connected the icord I continued with a icord bind off all around the edge for a nice bumper.
On my DH necklace (red/black) I picked up and did a icord bind off in the window for extra bumperness
