 Here is the coolest propagation tip from this book. First, soften air drying modeling clay. Shape it into a ball with your hands and use your rolling pin to make it flat until it is around five millimeters in thickness. Place your propagation jar in the middle of your circle and cut it to be two centimeters bigger in diameter than the opening part of your jar. Make a hole in the center like this one. Shape it into a funnel and wait for 24 hours so it dries. Once it has dried, decorate it with oil paints. Add a layer of varnish to protect the paint and once it dries it will help you prevent the leaves from touching the water.
