The bird's egg is made so you can work on top of each stencil-print and thus get a nice effect of a spotted egg.

On the first picture, I have used only two of the egg stencil patterns. The egg itself is about 30 cm tall.
On the other pictures I have used all four stencils on top of each other. It is called a multilayer pressure. I have printed on heavy paper with a good paint.
