This print is on its way to Illinois for Real People 2015! When I was making this series of home prints I would take pictures of the different stages. I only have photos of the first 3 stages of this one, but it's easy to imagine the last 3 or 4 colors.
Going into these I would start with an overall sketch and a plan for what colors I would use and where (at least the first 3 or 4). I would paint each stencil one by one and adjust the colors as needed as the print progressed.
Looking at the first few stages actually gives me an uneasy feeling-- it is so open, there is so much room for something to go "wrong" (anything from a slightly off color to a registration error). And the more you print the more you're committed and the more that's at stake if the next layer doesn't work. But, it's a rare mistake that can actually ruin a print (especially for silkscreen). There's usually a way out, even if it leads somewhere unexpected.
