I love stencils, like stenciled-all-my-bedroom-furniture-in-college-with-a-stencil-I-made love stencils, so I’m pumped about this book and book signing event coming up this Saturday (Dec. 5.) The book, Stencil 101 Decor, features 10 DIY recyclable plastic stencils and tells you how and where to use them. The author is Brooklyn-based graphic designer Ed Roth, who fulfills every stencilicious whim, from poodles to sumo wrestlers on his site, Stencil1. He’ll be there Saturday to provide hands-on stenciling lessons for all ages. The event’s from 4 to 6 p.m. at the powerHouse Arena in DUMBO (37 Main St.), and stenciled edibles and chocolate are included. To sign up, email rsvp@powerhousearena.com. More details here.
