Once you have made your river leading to the edge of your cliff, you will need to measure the distance from the top of the cliff to the bottom, then add approximately two inches (5cm) to your measurement.
Using a piece of grease-proof cooking paper or a non-stick baking tray, pour realistic water onto the paper/tray to the length required. Check that you have enough width and leave to dry.
When dry, peel off and you will have a thin sheet of realistic water that you can then add to create that waterfall.
