Different street art methods are described including stencils, tiles, knitta graffiti, and spray paint. Stencils involve applying pigment through cutouts in an intermediate object to create a pattern. Tile art can include larger decorated tiles or mosaics made of smaller tiles. Knitta graffiti originated in 2005 involving wrapping public structures in knitted materials. Spray paint art is applying spray paint to non-porous surfaces and sometimes features surreal landscapes.
