Party favors are a great way to leave an impression on your guests. You don’t have to—nor should you—blow the budget on them. For instance, these custom oyster napkin rings can be replicated by going to your local beach and picking up shells. If the beach is not an option, you can opt for your local craft store or even your backyard where stones or rocks painted with silver spray paint can create a similar, DIY-chic effect. Feeling extra festive? Use paint or a marker to add a monogram of your guests' initials.
