Illusion Knitting

Started a new project last night, the "Alien Illusion Scarf" from the Stitch n Bitch handbook. You have to work at the pattern from a chart...which scared me a little, but once I got it all cast on, it was fairly easy...and wow at the results!!! One side is fairly obvious, but the right side has a kind of holographic effect. Look at it flat and you can't see anything, but look at it from an angle and you see the alien face......so clever!!!
