Illustrator for Lunch™ is a series of short video courses you can study in bite size pieces such as at lunchtime. In this course you'll learn to create corner tiles for pattern brushes in Illustrator. If you are using Illustrator CS6 (or earlier) Illustrator won't provide sample corner tiles for you to use so you need to make your own - I'll show you how. In Illustrator CC 2015 you can make your own corner tiles if you don't like those that Illustrator provides.
