Line art makes a simple yet striking addition to modern-day gallery walls, but the technique dates back thousands of years to some of the earliest cave drawings. Linework was later popularized by renowned artists including Henri Matisse and Pablo Picasso, and contemporary versions often draw inspiration from these earlier works. You’ll now find examples of this understated style on wall art, ceramics, pillows, wallpaper, and more. It’s particularly popular on sites like Etsy, where a search for “line art” yields more than 300,000 products, but you can also shop line art decor at retailers like Target, Pottery Barn, and World Market. Some of the most popular line art designs represent abstract faces or bodies with curving forms. These figures are often created with a single continuous line that loops around the paper, resulting in an expressive, sketch-like drawing. These minimalist pieces add subtle contrast amid bold colors and patterns, but they can also beautifully complement neutral interiors. Add line art to balance a busy gallery wall, or layer a squiggly lined vase or planter among eclectic bookshelf decor. Here are some of our favorite pieces of line art to incorporate into your space.
