Knots/Sinnet knots/Daisy chain

• 
  Start with a slipped overhand knot.
• 
  Keep passing bights through.
• 
  End it off by putting the working end through the loop.

One of the features of the daisy chain (AKA chain sinnet) is that it can be untied by pulling the end out of the last loop and pulling on it, which will pull out every subsequent bight.
