A skeleton key is such a versatile shape for a wallhanging or shelf decoration. It works with lots of different decorating styles too, from steampunk to vintage to industrial. This faux-rust technique is really quick and easy – it makes the lightweight Smoothfoam look like rusted heavy metal!
Smoothfoam sheet (any size)
Black acrylic paint
Clear spray sealant
1. Sketch or trace a basic vintage key shape on to Smoothfoam sheet in whatever size you like. Cut it out with a craft knife.
2. Sand all the edges of the key with sandpaper until smooth.
3. Paint the key black. While the paint is still wet, sprinkle cinnamon in random areas to simulate rust. Let dry and then spray with clear sealant spray.
