A free digital illustration tutorial from CartoonSmart’s most prolific Adobe Illustrator instructor, Brian Zaikowksi. His Exploring Adobe Illustrator series is literally a day’s worth of video tutorials (over 24 hours). The video above is just one lesson from that series, and although this course uses a slightly older version of Illustrator, you’ll notice the tools really haven’t changed (when it comes to product updates Adobe rarely messes with a good thing).
In this particular lesson, Brian will show you the power of Art Brushes. He can explain it best, but in short, you can draw using the stroke tools then apply brushes / patterns to the line afterwards.
