If you're using studs, you're going to need a special hole punch. It's a tiny 1/16" hole - that's about the size of a bold full stop! The studs are not sharp enough to punch through card themselves.

These Fiskars brand hole punches are top quality and will last for years. They're plier style and have got a comfort grip handle so even if the job's big, you'll get through it without pain! 

TIP: When doing your layout, print a dot where you want your stud to be to make positioning the hole a sinch! We take the catcher off these plier punches so it can be used upside down and you can see where you're punching.
