Sorry I am not doing a good job of explaining this. I don't want to copy an existing item. I want to start with a picture and turn that into a carved "half piece".
I only need one side shaped and the other side flat so I can attach it to a box.
I have used my scroll saw and cut out shapes for boxes. The shape has 3 dimensions but I can't change those dimensions across the piece.
What I have done, for example, is find a side view picture of a bird on the internet, print the picture, transfer that to a piece of wood, and cut it out with my scroll saw but The bird shape will be the same thickness across the entire piece of wood.
I want to be able to have his belly or bill etc. be thinner or thicker than the rest of the shape. I want to produce what Theo has in his last picture of the eagle but not copied from another piece.
