Nils Westergard created this skull using a stencil on wood. Nils is a street artist, who normally works in large scale. He creates stencils ahead of time, which he uses to mask areas while spraying around them. Want to try using a stencil yourself? Noah has 9. Stencil Skull, 232. Stylized Stencil Skull, 319. Two-Part Stencil Skull, and Laughing Skull available for your use. Don't forget to submit to us what you create using any of the Free Stuff, and we'll likely share it.
