Your invitations are the first impression guests get about your wedding, so take time to get it right. Look at sites selling invitations online and in magazines such as Wedding Ideas as they can provide inspiration. You will soon learn what you do and don't like.
However, if a paper cutter sounds like a useful thing that has a place in your office, buy it! You don't need to shell out 贄 for a good one. This ษ trimmer has been a great little workhorse for me for about four years now, through invitations, photo albums, and many, many other late night print jobs.
