The Houston Antiques Dealers Association holds its biannual Spring Antiques Show & Sale — the oldest antiques show in the country — Friday through Sunday, March 5 through 7, with 150 prominent dealers from around the world setting up wares at the George R. Brown Convention Center. We’re intrigued by the American Society of Interior Designers booth, which will offer 15-minute, one-on-one “Ask a Designer” Q&As for the public (complimentary but by appointment only). Proceeds from the event benefit the Houston Heritage Society and Houston Junior Forum. Tickets $10 at the door. To book an “Ask a Designer” appointment, visit asidtgcc.org.
