Volume 3 of these Adobe Illustrator brushes have been created from real hand-drawn fine-liner and permanent marker strokes. These have been vectored in a way that keeps the texture and shades of color still visible in the brush and are set to adjust to the color you have selected.
If you are in need of brushes that produce a realistic hand-drawn appearance then these brushes are for you!
The majority of brushes are quite thin, this is done purposely so that you can use fine details in your design. If you need thicker strokes, then simply bump up the stroke width until it is at your desired thickness.
