It's that simple:
Glue the Lamp foil on top of each other on 3 cm and cut them off at a total length of 97 cm. Leave the protective foil on it!
Now lay the Lamp foil on the fabric and draw the outlines.
Spray the fabric within the marking with all sprays except the Black in batches and let it dry.
Spray the Stencil on one side with spray adhesive, place it on the fabric and spray the motif with the black paint.
Wash the Stencil immediately after application.
When the paint is dry, iron the fabric inside out.
Pull off the protective foil from the Lamp foil and stick it into the marked fabric surface. Leave 3cm free for the adhesive surface.
Now cut the fabric with 1 cm addition.
Apply-Ribbon tape inside the foil and fold the fabric inside out.
Glue the Lamp foil together.
