Maker Faire Bay Area (part 2) - May 19th 2013
I bought this interesting new dye that is reactive to light, called Lumi Inkodye. You can print a photograph directly onto a T-shirt by coating the T with this Inkodye and exposing it to the sunlight for 20-30 minutes. This is the quickest way to print on fabric permanently!
