Frozen cocktails are a cool way to kick off your after-party—and making them self-serve ups the fun factor even more. You can rent a machine (margarita mannyc.com), which comes with margarita mix (or one of the more than 20 flavors offered), and add your own spirits. Custom removable signage helps it fit into your palette or theme (download our fiesta-worthy sign at marthastewart weddings.com/margarita-signage). Set out glasses, garnishes, and drink stirrers— we like citrus jalapeño salt ($7, rokz.com) and green flamingos ($18 for 6, therocshop.etsy.com)—for revelers.
