Fiskars Border Corner Punches are two punches in one. Create continuous borders or use the corner punch button to transition into frame... Full Description & Details.
I am finding this punch very difficult to line up and it's hard to punch. Maybe it'll be better once I break it in but as of now (I just got it yesterday) I am not impressed.
I love the Fiskars Border/Corner punches. Great designs, and very easy to use as long as you work in 1-inch increments (12x12, 11x11, 8x6 and on and on).
Directions are on the back of the package. There is a small learning curve, but I thought it was easy.
