Apply a layer of napking glue to fix the image to the transparency. Be very careful, however, as not to destroy the image. Leave until dry.
Cut little holes into the canvas just below the windows.
Take the light chain and put one light into each hole (from back to front). If necessary, use adhesive tape to fix the lights on the back of the canvas.
Cut out the image from the transparency.
On the back of the image, apply glue to the lower part only.
Glue the lower part to its counterpiece on the canvas. The upper part of the transparency will (hervorstehen) overhang a little, due to the lights behind it.
