Step 1 Place the paper napkin quarter in the frame. Lift up the edges, one after the other, and mark out in gray pencil the areas where you would like to create a 3D effect. Here we've marked out the scarecrow and pumpkin shapes etc...
Step 2 Work the modeling paste a little (it will quickly go dry in your hands) and stick it onto the areas you've marked out.
Step 3 Separate out the layers of the paper napkin quarter. ¨Place it on a piece of cardboard, face down. Spray it with glue/varnish from a distance of 8 inches. Wait a few minutes, then place the napkin inside the frame, making sure it's straight.
