Just finished another pattern. It started as a doodle and I liked it so much that I turned it into a bigger drawing.
^Here it is in progress^
^The finished main square^
After I finished the main square I split it up in photoshop, printed it out, and filled in the remaining parts to make it repeat seamlessly. Then I scanned it in again and lined up that part to the main square.
It wasn't looking right with full blown color so I decided just to color the lines.
