Hi Ditchfield
1. Take a loop of paracord (what ever lenght you wish 10 feet would be nice)
2. Fold it in half so that both sides are equal in length.
3. Tie a simple overhand knot with the folded paracord at the looped end. - you should end up with a knot with a looped end. You can use this loop for the button to go through.
4. WIth the free ends of the paracord, tie square knots repeatedly (right over left, tie, then left over right, tie ) till you reach the end.
5. How you end is up to you. If you don't need a bracelet, you could just secure the ends with cable ties. If you want a bracelet, you can sew a button to the cable tie ??. <img src="images/graemlins/grin.gif" alt="" />

6. Experiment and have fun. Adjust the knots and the tension to make it look nice if you want <img src="images/graemlins/grin.gif" alt="" />

Quite a fun project. Who knows, you can make up some and sell them on ebay too and give the guy a run for his money!
