I am a novice and am having trouble going around the page but it does give a nicer corner to pages instead of straight corners. Eventally, I'll learn how to use both the corner and edge around the page together. With the edge I did found it doesn't work properly with pearlized paper which was disappointing. However, I love the corner punches.
I really like all of the Martha Stewart punch around the page punches that I have however, I wish that I could figure out how to make more useful sizes than the ones that they say are standard on the instruction sheet.
