This simple (if over worked) Instructable (my first) should show you how you can use those annoying bits or Paracord that are often left at the end of making just about anything, but are to short to be of any use.
These rings are purely decorative, you wont see them getting Bear Grylls out of a tight spot anytime soon.
Step 2: Size and Meassure your cord
Measure this against your ruler for future reference.
Make sure that any ends that are sealed or tatty are not counted in your measurements as these will be cut off.
Once you have the right length for your finger add extra 1/8" to 1/4", this will be used in the joining of the ends.
Step 3: Cutting and Gutting
If the other end is sealed or tatty remove it as well.
Pull out and discard the central fibers.
Make sure you do not reseal either end at this stage.
Step 4: Shaping and Sealing the ends.
Role one end between thumb and forefinger to try and close it down as much as possible.
With your flame lightly melt this end sealing it.
Careful molten Paracord can be painful.
When sealed the end should be as small as possible, it does not need to be completely closed.
With the other end use your tweezers or hemostat to lightly tease the in open and again lightly seal it with your flame.
There should now be one smaller nearly closed end and one widely open end.
Step 5: Closing the ring
Use your tweezers to push the it in further.
Check the size on your finger to make sure its not too loose or tight.
