Try to follow me. This may be tough.
After you have wrapped the serving thread about 6-8 times toward the peep,take a seperate piece of thread,fold it in half so you have a loop on one endand lay it on the string over the wraps w/ the loop end laying in the direction you are going. In this case ,toward the peep. Now wrap loosely 5-6 times over the piece of string (Loop) and take the tag end of the serving and run it through the loop. Now pull slowly the opposite end of the loop through the loose wraps. (Pulling thisopposite the direction you were serving). The loop should pull throughthe loose wrapsand leave a tag end of the serving. Pull it tight along w/ the opposite tag end you started the serving with. Cut and burn.

If u can understand that w/o pics. ,,, you da' man. Good Luck.
