I've been wanting to dye a cotton jacket to a different color so I've been reading a bit about fabric dyes. Apparently you can buy actual fabric dye and just mix a little bit of it with water to create a "paint," and use a paintbrush to paint the color on. This is what people do to color silk scarves and tee shirts. But in all seriousness this technique will probably not look any different than using a sharpie in this case. This is all true.
