This is a set that I created and use regularly  myself, and come back to time and time again. The brushes in this free set are varied and versatile, allowing you to create a hand-drawn sketched look, as well as decorative borders, curls and doodle style illustrations.  Put the .ai file in your Adobe>Illustrator>Presets>Brushes folder. These are for personal use only, unless you buy the (cheap!) commercial license from my shop. I hope you’ll get as much use out of these as I do.
