To make this mosaic you will require a canvas, eggshells, mod podge or white glue, white acrylic paint, thin decoupage napkin and a brush. First of all wash the eggshells with plenty of water. Break the shells into small pieces when dried. Then apply glue on a small portion of the canvas and stick the egg shells. Cover the whole canvas with egg shells by applying glue in parts. When the glue has dried completely, apply a coat of white acrylic paint. When the paint has dried, apply a coat of glue again and stick the napkin to the canvas. Press gently and a mosaic will appear. Happy crafting!
