Seeing this in the Stitch'n Bitch book, I couldn't really imagine it, so I tried it - but as a pillow case, not as a scarf, and without the poisonous-looking green. The only problem is that after sitting on it a couple of times, the effect is a little destroyed and difficult to fluff up again to make the alien reappear... washing might help but I did the seams so neatly that it will be difficult.
