Strip any old paint or finishes from the table, using the paint stripper and rags and placing a dropcloth under the table. Follow the directions on the paint stripper. A more environmentally friendly alternative is to use a sander. Sand the end table and wipe down with a damp rag.
Paint the end table with a base coat of paint with a paintbrush. Allow to dry and apply a second coat, if desired. You may wish to sand, with a fine sandpaper, in between coats. For design variations, consider painting the table top one color, and the legs of the end table a coordinating color.
Apply marbleizing from the faux marbleizing kit to the top of the table, if desired, following the directions on the kit. If stenciling, stencil designs on the top of the table. Add some complementary designs to the legs of the table for a more interesting effect, or allow the design to overlap the edges of the tabletop. Allow all decorative paint to dry.
Varnish the end table, if desired. Follow the directions for the varnish. Allow to dry.
