I don't remember where I read this, but it certainly helped relieving my frustrations using the cropodile to place brads & eyelets. I could never get them to line up straight on my card.
Using an old credit card, or one that come thro the mail, punch a hole using your cropodile 1/2" in from the corner and 1/2" down. One the other side do the same using 1/4" measurement. Now when you need to punch holes for your brads, or eyelet, you will have a template.
Just remember to turn the card around at opposite ends of your paper or your holes will not line up. Front of card at top, hole in left side punch, flip card to punch bottom hole, flip left to right for right side punch, flip bottom to top for final punch
I hope this is understandable and helpful
