TutsPlus - Master Patterns in Adobe Illustrator

Patterns are fun and full of endless possibilities, and we can see them
everywhere, from cell-phone cases to textiles. In this course you will
learn how to create your own geometric pattern from scratch and how to
save your own pattern libraries. You will learn about the Pattern Options
Tool and how to alter, fix and customize your pattern and create new
patterns out of it. You will also learn how to create your own custom
pattern brush. Once equipped with a good understanding of pattern and
pattern brush creation, you will go on and create a complex custom
vintage pattern from scratch.
