Creating Illustrator Brushes

First in my sketchbook I drew different patterns for Illustrator by using a ruler for the straight lines to keep my artwork neat and then using equipment like coal. chalk,ink and graphite.They all make different textures and patterns to make the lies different and more effective.

Then I put them onto an Illustrator sheet and made them more bold and put each pattern onto my own patterns so now i can use these in any work on Illustrator.
