One of the most popular exhibits at the Iowa State Fair is the iconic butter cow. Now the Des Moines Public Library is offering patrons the opportunity to try their hand at the art of sculpting with butter. The library is offering two sessions on Thursday, July 28, where participants can learn from butter cow sculptor Sarah Pratt. According to information on the library’s website, there will be two classes offered, one from 5:15 to 6:15 p.m. and another from 6:30 to 7:30 p.m. Both sessions will be at the East Side Library on Hubbell Avenue. It’s open to all ages, but children must be accompanied by an adult. Each participant will receive their own stick of butter to sculpt. Afterward, they can take their art home with them or give it to Pratt to be mixed in with this year’s fair exhibit. Space is limited and registration will close at 5:15 p.m. on Wednesday, July 27. Pratt became the fifth sculptor of the butter cow and other figures in 2006 after Norma “Duffy” Lyon retired. Lyon died in 2011. The butter cow was first introduced to the Iowa State Fair in 1911. This year’s State Fair is scheduled to run Aug. 11-21. Photo courtesy of the Iowa State Fair
