Everyone has their own way of creating a comic strip, but this, generally speaking, is how The Rainbow Orchid takes shape...
Before I start drawing, I need a script, but before I write the script, I need a plot. Story ideas are seldom delivered fully-formed. The rough shape will come first, perhaps as a result of several months' worth of disparate ideas coming together while I'm in the shower, or perhaps because I sit down in front of a notebook with just a single scene in my head, and start conjuring up characters for it to see what they get up to. Often a bit of both.
Even then it will only be a prototype. I find my stories need a few weeks (or months) of slow cooking and problem solving before I can start outlining the plot in any detail. And that's what happens next. By now I'll have accumulated quite a few pages of notes. Handwritten jottings tend to be the work of white flashes of inspiration or some dedicated free-form thinking, but there'll also be an assortment of pages typed up on the computer featuring more solidified ideas in various stages of progress. Gradually, problems are solved and the story takes shape.
