Let's experiment with light sensitive textile dyes, courtesy of Instructables (http://www.instructables.com/) and Lumi (http://lumi.co/)! Lumi is a new DIY alternative to screen printing. The process works on any other natural & absorbent fiber. Once finished, your print is permanent and can be machine washed without fading.
Since we're the science nerds, we'll also give a quick introduction about the science, alchemy, and even microbiology of the mysterious indigo and other pot dyes that the Lumi Inkodye technology is based on.
Make sure to bring some natural fabric to print on! T-shirt, blouse, underwear, pillow case, lampshade, raw leather, wood, or just some art paper. You may also want to bring something to print onto your fabric: a negative on inkjet transparency (check out the Lumi app (http://lumi.co/pages/app)), or just some interesting leaves or other objects. Lots of ideas on the Lumi website (http://lumi.co/pages/process)!
Be warned: we may also deviate a bit from the officially approved uses for these dyes - experiment at your own risk!
We may also do some experiments with anthotypes (http://www.alternativephotography.com/wp/processes/anthotypes/anthotypes-making-print-using-plants): printing with photosensitive flower and plant extracts. If you want to give this a try, bring (a) some petals from a colorful flower, berries or other plant material (carnations, violets, poppies, rose petals, spinach, red wine, beetroot, carrot, onion - you name it!), (b) some negative to print, and (c) a picture frame in which you can clamp the paper and your negative together for a few days to weeks.Lastly - make sure to take some pictures! And help us out to put together some kick-ass instructables (http://www.instructables.com/id/How-to-make-a-great-Instructable/) on all the crazy stuff we came up with during this build night!
