This one is special. I really just felt like coloring today, and I've wanted to tackle this particular image for a while. What a challenge! It's known as the Flammarion Woodcut and you can get the uncolored image from its Wikipedia entry. There are numerous colored versions around - see some of them on this page. The first one was my own primary inspiration. I used Derwent Inktense pencils and a sparkly gel pen for the edges.

You can see from this page that an image from the reverse seeped through. This happens when I tea dye the printed sheets, and only with images. Not all images do it, though. I'm not positive, but I think the problem is that some pictures that look black and white are actually not, and contain small amounts of blue ink. The blue ink on my printer isn't water-resistant like the black is. I'm okay with this effect though because it makes the paper seem transluscent, like real parchment or vellum is.
