Texture can add richness and character to a vector illustration, but often those qualities come at a price. Most texture effects in Illustrator are actually raster based, with limitations on size and quality. Here’s a quick way to create a versatile vector texture that can be painted on with a brush, right where you want it.
Step 1
Draw a rectangle, 1 point x 1 point.

You now have a stroke that contains a graduated texture, with enough randomness to look organic. Your Appearance panel should look like the image below.

For a tidier look, apply a Clipping Mask to the shapes to contain the texture.
