On the third Sunday of every month, folks gather at East Nashville’s The 5 Spot and with dry media (no paint, please) sketch images of beautiful young women donning equally eye-catching costumes. The models — both hot and not so much — include a panoply of pop tarts. You’ll see roller derby girls, burlesque babes, body builders, drag performers, magician’s assistants, contortionists and ballerinas. (What, no beauty pageant contestants?) Founded in Brooklyn in 2005 by the comely Molly Crabapple — who on her website notes, “I draw saucy Victoriana for magazines” — Dr. Sketchy’s Anti-Art School now offers branches in approximately 58 U.S. cities and in various international locales. A few interesting tidbits: Dr. Sketchy’s pays its models; the lovely lasses are often scantily clad (but never nude); it’s best to bring your own sketchpad and drawing instruments. The D-Sketch motto is simple: “Dr. Sketchy’s is what happens when cabaret meets art school.” With that introduction completed, it’s time to sketch a tightrope temptress.
