PlumSiena: What a Wall! Emily Swift-Jones She began with a normal, painted wall, smoothed it out with joint compound, primed with shellac and then went to town. The steps included Dutch metal gold leaf, patinating the gold leaf, glazing with oil colours and varnishing for the top coat. At the end, she embedded tiny glitter flakes into the tacky varnish.
The technique used here seems like a great way to get very clean painted stripes. One key tip - paint over the tape with the color beneath it before painting the other color. The first coat of paint acts as a sealant and prevents the second coat from seeping under the tape.
