Certainly! I start with a B&W photo (or desaturate a color photo), then use the trace bitmap feature on inkscape to create a multi-layered stencil (typically 5-6 shades of grey)... Then, take it to GIMP and clean-up. Weeding is surprisingly easy, just start with the darkest and work to the lightest (typically all of the shades are immediately adjacent to the next shade, so stay working within one "boundry" and you'll be golden). For dye times, from darkest to lightest, 7 minutes, 5 minutes, 2 minutes, 2 minutes, and the 5th layer stayed masked the whole time.
