Response from Sara:

Hi Jenni,

Thanks for your comment...I also love this punch! I talked with Susan about ways to make punching less of a workout (unless you want the workout!) and she shared these tips:
The punch works great on standard-weight scrapbook paper, but it's much harder on cardstock. If you want to use these punches with cardstock, make sure you have your punch on a sturdy table and stand up when using it, so you have that extra leverage. Place both hands on it (one hand over the other) to get the best pressure. If the punch is dull and won’t work well with regular papers, aluminum foil does help to sharpen it, and waxed paper might also work.
Hope this helps, and enjoy your punch!
Sara
