I use the end of a very small allen wrench to fray the end of the loop material and my finger tip until I get a dime sized fray. Then first melt it slowly all around the outside while turning the material and it will soon satrt toburn. I watch it until the ball gets to the size I like and blow it out. Don't touch the ball until it's cooled very well! I then cut the material to about 4 1/4 inches and fray and burn the other end, just about right for me.
