Once the paint has dried, the entire tray is coated with napkin varnish . napkin varnish does not only serve as an adhesive, but also as a top coat. The protective varnish allows it to be wiped off later with a damp cloth.
Now stand the smaller tray on end and decorate it with a small toadstool, Iceland moss and the hedgehogs on the tray, fixing them in place with hot glue.
