To make these beautiful flowers you will require lots of pistachio shells, a hot glue gun, discs of cardboard and spray paints in different colors. Start by gluing pistachio shells as shown in third picture on the centre of the disc and keep on gluing the shells in a spiral manner. Glue the shells closely spaced in the middle so as to form the centre of the flower. Once you get the flowers ready spray paint them in the colors of your choice. Now if you want you can decorate them by placing in a glass dish or you can glue them to a square piece of burlap and frame it. Enjoy crafting!
