How to create the luminous image
First paint the cardboard frame with gold paint. Then design the paper silhouette with craft paints.
You can create motifs of 18.5 cm in height in the frame, but when cutting your piece of paper silhouette, include 1 cm more for a gluing edge and then cut out corresponding parts from the Long Silhouette.
The 3D look of this image is created by crafting silhouette pieces in three different heights, one behind the other:
Extend the middle and back pieces accordingly each with glued white clay cardboard. Then glue all three silhouette pieces behind each other with double-sided tape and then into the cardboard frame.
