This is how the punch looks normally, with the guide piece on. I have cut a 1" x 4" piece of cardstock that I can add to the edge of a card. This dimension and technique was used on my Hostess Appreciation Event invitations. I can't show you those quite yet as they aren't mailed and I don't want to ruin the surprise. Once they are mailed, I will show you the card idea and share dimensions, etc. :)
Place the cardstock back in the punch and line up the edge of the first punch with the upward curve of the punchout area. Continue this step along the edge of cardstock until the entire edge is scalloped. Always work from the center to left, then center to right to finish the edge.
Ok, we're off to Balloonfest soon. Gotta slather on sunscreen and grab my camera. See you again soon!
