Pick out the color and size of fake lilies that you want for your glass bowl.
Add about 1 inch of colored glass stones to the bottom of the bowl. Add more or less depending on how you like it.
Fill the glass bowl with water about 2 inches below the rim of the bowl. You may need to adjust the level of the water by taking some out or adding until you are pleased with it.
Take the lily flowers off the stems if they are detachable or cut them off with wire cutters. Cut the stems short so there is a little stub left under the flower.
Put the lilies in the water. How many flowers you add will depend on the size of your bowl.
