I'm glad you revisited this one from VSN. When I tried it before all I had were small balloons that I just couldn't get anything in the neck. This time I went with a vinyl glove. Added a handful of buttons from my sewing room, shifted them to the palm of the glove and stamped with that. You can even see the holes in the center of some of the button images for the thread. This worked so much better and totally no frustration with stuffing a balloon.
