The wedding favor is one of those traditions that is evolving rapidly. Favors used to be limited to some Jordan almonds wrapped in tulle, but now favors can be just about anything from wine stoppers to playing cards. Take a look at some creative favor options.

Sunglasses make a great favor for any outdoor wedding (especially a beach wedding). Potted succulents not only make a pretty favor, they can double as place cards. A photo booth is always a fun favor option. The bonus of a photo booth is that you get a favor too (have two copies of each photo printer--one for the guest and one for the bride and groom).
No matter what, edible favors are always popular. When in doubt, give your guests a yummy treat!
Any of these favors would leave your guests smiling, and I promise you, there won't be any lonely favors left forgotten and stranded on the tables.
