Any image or pattern created by assembling tiny, colored pieces of hard material like stones, tiles, or glass is considered a mosaic. DIY mosaic projects are enjoyable to complete and can look fantastic for being made by hand. The brilliant recycling of used CDs, paper, beans, seeds, eggshells, and so many other materials has also gone into its production. Both interior and outdoor projects are fantastic. Create original decorations and stepping stones to add a splash of color to your yard. By covering a basic Mason jar with broken shells, you can create a stunning vase.
