This Celtic Knot was drawn over five non-consecutive days. It began as an ambitious project to keep me occupied during the slower hours at work. The entire process, minus the photoshop finishes, was completed on-site at my job. By far, my most complex knot ever.
I scanned in the picture after each night. I compiled them into a Quicktime movie, showing the stages of development. That movie is available here:BigKnot Stages
