These details do not have to be "Irish-y" or "St. Patrick's Day-ish" and can be incorporated into your event without it being an overwhelming theme. A four leaf clover charm can be added to a bouquet, a bracelet or necklace, a garter, or even a bustle. Cuff-links are a classic way to use four leaf clovers and a special touch if the groom has Irish roots! Or you could spread the luck to your guests by adding a crafty fabric or real four leaf clover at their place-setting.
Here's to being lucky in love!
