Ha! I don't have the kit, but that's the method. Longer focal length lenses use larger patterns- the photos above, using my 85mm, require patterns about 1" across (the front element is about 3" diameter), while my 24mm needs patterns smaller than 1/3"- too small for me to fabricate- I just print a design on paper and cut it out with a knife (under a microscope).
