First, you need either a Slit Punch or a Corner Rounder Punch (just be sure to take off the guide).
With a Corner Rounder:
With a Slit Punch:
You can see that with the Slit Punch, you need to trim your cardstock to about 1 1/4" or 1 1/2" in order to punch along the edges, because you will be working from the bottom up and punching along the top of the cardstock.
If you are getting crooked scallops, just be sure to rock the cardstock ever so slightly against the punch to make sure your cardstock is flush against the punch.
Don't forget to leave your thoughts or comments!
