This is a free set of eight Adobe Illustrator Swatch Patterns. These are seamless vector patterns that can be used to fill objects such as shapes, letters and words. Rather than using a solid color for a typeface, fill it with a swatch pattern. Drag these from the swatches panel to the canvas; change the colors. Drag them back to the swatches panel to create new swatches using different colors.
These are compatible with Illustrator CS and above.
