Maybe you're right Nicky, I'll finish it up and see.
The whole book pairs the hidden picture with the one you initially see (like an anchor to begin with that turns into a hidden sailor picture).
It was fun to do, seeing the hidden image appear!
It reminds me of the whole Magic Eye pictures. The ones you stare at that look like nothing but blotches of color, then Boom! You finally see a 3D image.
