One little Shadow Alien

Thin strips of alternating green and black? Yes, but it's so much more! Hidden carefully in Area 51... I mean in rows of knits and purls is a shadow knit Alien. Totally groovy, no? When glimpsed at an angle, you can see how this bad boy suddenly becomes less subtle. The technique is called illusion knitting or shadow knitting. The pattern is available in Stitch N' Bitch by Debbie Stoller.
