Faced with the task of quickly creating a repeating pattern I used Adobe Illustrator CS6 to create a group of wine bottles. Working in Illustrator can force a person into delivering very clean, almost clinically clean, work. So you have to choose your tools deliberately to break free from this pulling force.
Since I went for a loose, woodcut-ish look, I exclusively used the blob-brush. With a very small variable linewidth this brush can give a very nice ‘hand-carved’ effect. Creating the repeating pattern was a matter of seconds with Illustrator’s pattern tool. I used a hexagonal distribution and created some extra white space with invisible shapes.
