Punching fancy corners on your cards is always hard – there are glitches, such as the card catching in the cutters, or uneven placing, that happen so often that it is a good idea to cut the corners before doing any other work, just in case the card is ruined. This punch is no different. You will find it hard to place it accurately, and also that you have to pry bits out of the punch after each stamping. When it works, it's good.
