Using Patterns in Illustrator

You can make your own patterns too! Create the artwork you want to make a pattern from, select it and drag it to the Swatches panel and drop it in. Use it to fill any object or text (after using the Create Outlines command). You can also use seamless patterns created in Photoshop. Open the psd, png, or jpg file in Illustrator (File > Open), and then drag it to the Swatches panel. Use it as a fill the same as any pattern. Start with a high resolution image for best results.
