A great way to add an individual, hand-crafted touch to your wedding invitations is to add a deckle edge. A deckle edge is ragged edge, as opposed to a straight cut edge.
Deckle edge paper is specially made, but you can easily fake it with a ruler and a little patience. Here's how:
1. Take your wedding invitation print out (I'm using Botanical) and if there are two layouts, cut the page down the middle so you're only dealing with one invite at a time.
2. With a pencil, draw a very light line along the cutting edges so you'll always have a guide, even if you rip off your crop marks.
3. Lay a strong ruler (I used a metal one) along the crop marks of the invitation, and slowly rip. Make sure you hold down the ruler firmly.
4. Do this for all four edges.
