I have had four antique oak chairs with vinyl seats around my antique round pedestal table for many years.
On two of them, I painted only the vinyl seats with Annie Sloan Chalk Paint in Old White, and waxed them with clear wax.
The two chairs that had been previously painted black were given a couple coats of Annie Sloan Chalk Paint in Old White on the wood and vinyl seats.
I then stenciled the chair backs with Funky Junk Interiors Old Sign Stencils.
Much brighter and more farmhouse style!
