Fiskars makes great border punches. I have several and have used them over a period of years with great results. They are easy to use just follow the directions and you will have perfectly matched up borders and you can make decent squares and rectangles. Remember the corners wont be absolutely perfect, but they still look nice. This pattern has kind of a happy and fresh feel to it which would work wonderfully for a summer theme, a femenine card/page or a edge to a card to add some fun flair. The picture does not show the printed pattern on the bed of the punch that extends to the right and left that you use to match up the pattern as it is punched. It does get a bit difficult to push past 65lb paper, but is fine if you dont go beyond that. if you have arthritis it may be painful but you can use your palm and stand up to minimize that.
This and the other two border punches I purchased really added a lot of class to my cards. In fact, they have inspired me to push the envelope in designing and making my cards. The other two punches were Sunburst and Lace. In my opinion, all three punches are 5 star.
I've used it on several of my cards and it really adds a great look to them. By putting another color behind it you can change the look of your project. I'm very excited about it.
