I made some business cards with office libre and a printer. I put cardstock into my printers and printed off the template I made. The cardstock gives them thickness closer to actual business cards. They're a little narrower than standard business card.

For my cutting method is putting the paper on a cutting board, lining up a straight edge on line a razor to scratch through the paper and have it push against the straight edge to keep as straight as possible. I find this method to be faster than scissors
