From orchestrating a smooth game of bridge to serving appropriate foods, the Delineator Institute's manual "How to Give a Bridge Party" provided the 1920s hostess with all the details. Entertaining at home was an important part of the Roaring Twenties, and bridge was a popular pastime. A card game played in groups of four, bridge lent itself to social gatherings at which some Victorian-era conventions persisted. The Delineator Service Home Institute supplied the instructions for a successful bridge party, including planning, making, and serving the refreshments and awarding the prizes at the end of the game. Originally founded to provide Butterick sewing patterns to women, the Delineator Home Institute began as a fashion magazine in 1873 and soon branched into cookbook publishing. During the 1920s the Delineator line comprised mostly booklets, including Cooking for Crowds and The Hostess Entertains Her Club.
