First step is to figure out what size the geisha should have to fit on top of the handpainted fondant. I took a piece of paper and cut it up to fit the size of the painting.
Take a piece of baking-paper/see-though-paper and apply on top of your drawing. Place a tiny bit of fondant, and shape it to fit your drawing. Make it about 0,7 cm thick.
Use your pencil-tool to make eyes and cheekbones.
Now, make the body, starting with the neck.
Now the fun part begins:) Roll fondant (about 1-2 mm thick) and place it over the face and body. The skin-coloured fondant should cover both head and neck to make the best result.
Make arms and hair. Remember that the arm facing the painting/ background should be flat and smaller than anatomical correct arms.
