Paper Mache Bowls with Gelli™ Prints! To decorate bowls like these, draw leaf shapes on many pieces of Gelli printed paper using a copper Montana Acrylic Paint marker (Fine—2mm). With a black Montana marker (Fine—2mm), add dots around each shape. Each black dot is layered with a small white dot from a Montana marker (Extra-Fine—0.7mm). Then cut out each small leaf shape with scissors. It's a slow, detailed process—quite like a meditation!
