These pretty balls are beautiful and almost free. Use the bottom of a drinking glass (or other round thing that gives the desired size) as a pattern. Draw around it on a piece of cereal box cardboard. This is your template. Use it to draw a circle shape on the desired parts of old Christmas cards. Fold about 1/3 of the circle toward the center, picture side facing you, then repeat 2 more times. In effect, it's a triangle with 3 flanges. Do this to all the card circles. Use a glue stick or tacky glue to join all the flat sides until you have a ball, remembering to add a string hanger. Run a thin bead of glue over the exposed edges and 'dip' them in glitter.
