What is a Line? - CMYK Pen Patterns

I recently started experimenting with making my own patterns. I used illustrator to create a pen shape (as that is what my project is about) and then i shrunk it down, repeated it and then experimented with making it 3d and then creating patterns with them. I think it will be quite interesting to experiment with the negative space in the patterns to see what patterns they make and then use different pens in different compositions to experiment with positive/negative space and 3d patterns.
