I love old architectural elements and aged metal. If you catch me at the flea market I am hanging out at the vendors who sell this wonderful stuff. This is an example of Creative Paperclay® made to look like an old metal door detail.
Indonesian wood block
Acrylic paint (black & micaceous oxide)
Gold & silver rub
Apply Creative Paperclay® over an old Indonesian wood block or anything with lots of texture. Let the Creative Paperclay® dry completely.
When dry, paint with a matte black paint and let dry.
Apply gold and silver rub to the highlights.
For a final coat, apply a watered down micaceous oxide acrylic paint and liberally apply salt the wet paint. Let the paint dry thoroughly. The salt will adhere and gives it the gritty texture of age.
