Ringbolt Hitching Key Ring
My nephew wanted a large key ring.  He liked this.
I started with 6' of 550 paracord.  I left 6" tag end of cord at the beginning and began single strand ringbolt hitching around a 1 1/2" OD steel ring.  Tied the 2 ends using a diamond knot relative.   Had about 4" of cord left over .

I prefer this alternate ending. I took the two ends and tied them into a 4 bight, 3 lead Turks Head Knot. Saw the idea in rein endings in Bruce Grants "How to make Cowboy Horse Gear".



THe Turks Head Knot doubles nicely

You can find a tutorial for ringbolt hitching at http://pineapple.myfunforum.org/about1957.html  I can post the tutorial here if anyone would rather stay on site.
