Protect your workstation with a wipeable surface.
Take one of the two stretched canvas and spread white light texture paste over the entire surface using a painting palette knife or palette knife.
Draw a pattern in the paste with an effect spatula of your choice. If the desired look is not immediately achieved on the first attempt, the structure paste can be quickly smoothed out again for a new attempt.
After you have created the first stretched canvas in this way, take the second stretched canvas, coat it with structure paste and model the counterpart to the first relief using the effect spatula. Both stretched canvas should now dry for approx. 24 hours.
Paint the dried stretched canvas with acrylic paint in black or gold. Once this paint has also dried, you can attach picture frame hangers to the back of each frame of the stretched canvas and then hang the picture arrangement on the wall.
