The original instructions are at the end of this post.
Start by making the loop as shown here.
Now pull it all a little tighter, but still leaving a pretty big loop (1)there on the right.
Take your cord and make another small loop (2) and pull it through the big loop (1)
Now, make another loop (3) and pull it up through (2)
Now take a minute to tighten up all your loops a little bit. If you have enough cord, then make a few more loops, just like you did for (2) and (3), until you only have a little bit of cord left over.
Pull that little bit of cord through the last loop you made.
Here is the original instruction sheet. Maybe the arrows in the pictures can help you some more.
