A back-painted glass top is a quick, simple, high-impact way to add a splash of color to any room. Have a piece of glass cut to size; then use a large foam brush to paint the underside in a sky blue latex. Here, a 1/4-inch plate glass with a flat polished edge was used. Remember, the color will look greener through the glass. If you don't like the color, hose off the paint and try a different one. Ask your glass shop for plastic spacers (usually free) to keep the glass from lying directly on the tabletop.
