I get an idea, and I usually just run when it. Especially when the idea excites me creatively. A hour or so at Illustrator and I’ve got the planned mask laid out for the copper clad circuit board etching. The black lines with the +/- on them will be printed out on transparency film and hopefully I will get good results. The kit I have is a “positive mask” style, meaning I will have to reverse the image to properly mask off the copper.
