Glass pieces can be purchased through me if you can’t locate them. Circles measure 4". Unique designs in pen and ink with oil rouging. Easy to do; no tracing. Just clean glass with windex, 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 and voil’a! [I only stock the circles- patterns are enlarged to fit them.
