A while ago, we wrote about a swell garden party thrown by Jennifer Sweeney, the Libertyville-based paper-goods designer who loves all things girlie and has a gingerbread-cute house that also doubles as her studio. On February 3, from 2 to 8 p.m., Sweeney will host an “antiques and treasures” sale there, selling pieces of her own furniture and more. 417 Wedgemere Pl., Libertyville, 847-816-8387.
