To Riley, 35, art is about materials, texture, and color. She unexpectedly pairs crochet work with chunks of wood and linoleum, marrying the delicate to the brawny in fanciful, provocative sculpture ($1,200-$6,000). "I look at fashion, at architecture," says Riley, who also works as an interior designer, and used to build theater sets. "I'm always interested in traditional craft. Yarn is definitely like drawing." The artist expects to have a public art piece up in Somerville this spring. Genovese/Sullivan Gallery, 450 Harrison Ave., No. 47, 617-426-9738. genovesesullivan.com
