Patterns
Here I have created a pattern using Illustrator. I have done this by crating a star shape, using the shape tool and then using the roughen tool under 'distort and transform' under 'effects' to make it look how it is now. I then added the five stars and clicked expand appearance to make the shape all one. Then clicking, object, pattern and make I then chose how I wanted my shapes to be arranged on my pattern and also what shape and colour I wanted the background to be.
This could be useful to created backgrounds and also to make any textiles pieces which require a pattern.
