1. Find an old window frame at a junk shop or flea market or construct your own with salvaged wood and glass. Then draw our watering can motif or a garden image of your choice on a piece of paper. Tape the paper to the back of the glass with the image showing through.
2. Apply clear contact paper to the front of the glass. Use a craft knife to cut the image from contact paper. Remove paper from the back of the glass. Peel off sections of contact paper so the design shows through.
3. Follow the directions on glass etching cream, available wherever craft supplies are sold. Wear latex gloves. Apply the cream to warm room temperature glass with an artist's brush. Allow to etch according to directions. Rinse with warm soapy water. Remove contact paper.
