You can add a leaf to your flower by placing the petal shape perpendicular to the other petals of the candle, like so.

When you are satisfied with your flower, trim the wick on the bottom (stem end) of the flower flush with the base. Use a small triangle of warm wax sheet and cover the wick at the bottom of the flower, smoothing the edges into the flower to create a seal. This is to keep water from soaking your wick or seeping into the flower while it is floating in water

Another way to seal the bottom of your floating flower candle is to dip it into the leftover liquid wax, which you will have kept warmed to between 150 and 155 degrees F. This happens to be the perfect temperature for dipping candles.

Use pliers or your fingers to grasp the flower at the top by the wick, and carefully lower the stem into the liquid wax, pulling it out again quickly. Take care not to allow the top of the flower to dip under the liquid wax, as it will coat the inside of your flower, obscuring the face of it.
