100 Useful Free Textures
In Web design, texture is one of those elements that are widely used by designers, yet often hardly noticed by users. We don’t see them is because they usually remain in the background and supporting the overall design. Used primarily for background images, they need to fit to the overall design making the content easier to perceive.
Textures are not necessarily used in fashion-related or grungy websites; more often they are applied subtly to lend a personal tone to otherwise lifeless and faceless design elements. Textures are also often be used in combination with other elements such as typography, lighting and colors. They are most common for backgrounds, but are also use to fresh up a flat and boring appearance of design elements. Texture adds dimension to virtually any style of design, if applied properly. They also add a certain level of realism, creating a less formal, more inviting and aesthetically pleasing atmosphere that reflects our environment — after all, plain flat surfaces rarely exist in reality.
