How to do it
Download and print leaf template, enlarging to desired size to fit tray.
Remove backing from adhesive stencil film and smooth onto underside of glass.
Place template on a flat surface and place glass over template, film side up. Following the template through the glass, cut the leaf shapes into the stencil film with a craft knife. Remove the film from inside the leaf shapes.
Paint two coats of paint over the stencil, letting dry between coats. Remove stencil from glass.
Paint entire underside (painted side) of glass with gilding size. (Note: Size will be milky when applied and turn clear as it sets and becomes tacky.)
Apply patent silver leaf over size, and use a soft brush to remove excess leaf.
Place glass in tray.
