Glass pieces can be purchased through me if you can't locate them. Unique designs in pen and ink with oil rouging. Easy to do; no tracing. Just etch the glass, wash, dry on paper towel. Lay glass on packet design, look through the glass and ink away! Lightly mist with matte spray, scumble white acrylic on the BACK side of the glass, and spray that. Go back to the front- tint with oils, dry with matte spray. Designs do not have to be done on glass; enlarge or reduce to fit on slate pieces, wood, or tin that has been basecoated!
