Mix black gesso (a thick, water-based primer used to prepare canvases for painting with acrylic-type paints, which remains flexible when dry) with a bit of green (gesso is a fancy primer). Apply green paint (this may require two coats).

Stencil on Victorian-style stencils ready with the black gesso and a stippling brush (the gesso has a velvety finish); place the templates together to create a wallpaper effect.
After the paint has completely dried, varnish with a high-gloss water-based varnish to protect the stencil and give it a modern lacquer look. Replace hardware.
