Wrap the remaining length of string around the base of the branches several times to secure it. Then, gradually, work your way along the length of branches until you reach the leafy end. Return the string back up to the stems, creating a bit of a criss-cross pattern. You'll want to wind the string tightly enough that nothing gets loose, but not so tight that it cuts off pieces of the plants.
When you get back to the stems, tie the remainder of the string to the 2" loose piece you left at the beginning. Trim off any excess pieces so that the ends of your smudge stick are even.
