I can't show you but I can try to explain it. Take your leaf stringer and melt the very end to form a tiny ball. When you lay the ball down onto the bead, it has to be hot enough to move. Lay the ball down and drag through the ball in a downward motion so it brings the ball to a point but also leaves a ditch in the middle. When you do this, you are working out of the flame. As soon as you drag, go back into the flame to burn off the stringer.
This is like a dance. You just have to practice and you will get a rhythm going and you will be able to do it with your eyes closed and both hands tied behind your back
For the finish, you might have a ball of glass where the stringer was burned off. Heat your stringer again and the ball on the leaf and remove the excess glass to clean it up.
Hope that clears it up a bit.
