Many people including myself have had trouble following the Stormdrane youtube video on tying the lanyard knot so i have done some research and found the solution!
Step 1: Materials
All you need is a reasonable length of para cord or whatever you wish to use.
Step 2: First Step
The first thing you are going to do is to make a bight that leaves you with to congruent ends.
Then you are going to put your ring finger through the bight.
Step 3: Starting the Knot
Make a loop just like the one in the picture and place it over the top strand.
Bring the top strand under the bottom strand.
Step 4: The Most Important Part
Now you take the top stand from the previous picture and feed it over the first part of the loop under itself and back over the remainder of the loop.
Step 5: Doubling
Now take the bottom stand and take it around the part of the top strand nearest to the bight and than come up through the diamond shape in the middle.
Do the same for the top strand.
Step 6: Finishing
When you take it off your finger it should look like this.
Work out the slack by pulling on the bight and the two strands.
