Gently melt the gel in a pot on the stove over a very low heat.

When melted the gel will run like water.

Dip the silver sustainer on your wick into the melted gel and place it in your glass.  It will set and stay in position.

You can add some colour and fragrance to your gel.

Pour a layer of gel into your glass and leave it to cool.  Now you can drop in some glass fish decorations or any other.

When your first layer has set you can pour your second layer.  Leave your second layer to cool and then add more decorations.

Complete your candle in this way, layer by layer.
