Let the sun shine in! And with this wonderful twist on curtains or other typical window treatment, give any room a fresh, garden feeling. To do, cut a lattice to frame the window. Paint the desired color, when dry, nail to wall. Place a large pot or urn on either side, planted with ivy and fitted with a wire topiary form to train the vines into a pleasing shape. As tendrils grow and spread, direct them on the lattice. Water when dry and feed sparingly, the ivy will fill out the wall around the window in no time.
