I made this sweater about 20 years ago when I was in my Escher lizards phase. (I also made a vest and pillow!) I graphed the pattern myself & knit it up on my Passap knitting machine. I’m posting this now because there is an ongoing Ravelry discussion about knitting Escher designs.

UPDATE 3/18/11: Per many requests, I managed to locate my original graphs. Although they’re designed for my knitting machine, I think they would work for hand knitting too. I.e., I chartered them for the elongated stockinette stitches. (The red & white one is the actual punched card). You can PM me if you want either in PDF format.
