Thank you Darla! You need a good bone folder like the one SU! sells. Also the Mat Pack is helpful. How I do it, is put my card stock on top of the soft piece of the Mat Pack with the hard piece under that. Then place your grommet onto your card stock and push the teeth into the cardstock and the soft mat. Then when you turn it over you will see the teeth have come through to the other side. Take your bonefolder and push each "tooth" outward and flat. HTH!
