Knitted Optical Illusion

Do you remember the optical illusion where you see either the young girl or the old lady? And sometimes you have trouble seeing it the other way?

Well recently I knit this cute little leaf for a luggage tag. To me, it was nothing else but an leaf, but both the kid and Jp walked into the room where it was drying and asked me why I made a gecko. Okay, I can kinda see how they thought that, but to me, it's still an oakleaf.
