To make each of these ladybugs first you have to take a bowl and line it with plastic wrap. After that make a mixture of cement and sand in water and pour it in the bowl with plastic. When the cement and sand mixture dries take out the semi sphere. Put it on a working surface and fill all the rough surface with cement mixture and even it. Then with a pencil make the dots, wings and eyes of the lady bug. Then take red and black pieces of tiles and cover the ladybug with them using a tile adhesive. Place these beautiful bugs in your garden. For more details view the tutorial at handmade idea.
