I just found this cool Kickstarter project. It’s the Lumi Process, “a revolutionary photographic print process for textiles and natural materials.” It allows you to print photograms and other art onto natural fibres. The dyes develop with a few minutes of sunlight and then you wash the undeveloped dye out with detergent.
People have already made lots of great stuff like this with this process. Get yourself a kit or start your own business!
By the way, if you want to embed a Kickstarter video on WordPress.com like I just did it’s a little tricky. You can find out how tricky here.
