Silver foil is used as a base layer on the samples above and below. On the Savoy Silver sample, it is used under the Ebony Frost Lusterstone Stencil and on the Glazed Grainitine sample, the foil is under the Sandstone Plaster.
This looks so cool - taking a repeating wall stencil and painting with metallic paint. Adds such dimension and visual interest. I'd imagine you wouldn't want to do this to an entire room, but an accent wall would be so awesome.
