Chop the Crystal Honey into chunks and place in a microwavable jug. Whilst this is heating through, cut out bubble wrap (bubbles facing upwards) to fit into the bottom of your mold.
Once the base has melted and is a smooth consistency throughout, pour into the ice cube or ball-shaped molds to create your embeds.
Once set, remove the embeds from their mold. Chop the Crystal ST into chunks and place in the microwave to melt.
Whilst the Crystal ST is melting, pour the Crystal Honey into the mold on top of the bubble wrap layer. Fill to just over an inch.
Once the soap base in the mold has set, place the embeds in neatly. Fill the spaces using the Crystal ST until the top of the embeds are covered. This is your first layer. Repeat this step once the first layer has set, creating a second layer (image below).
Place bubble wrap face down on top of the soap and leave to set.
Wait until your soap has properly set before removing the bubble wrap and taking the soap out of your mold.
Viola! Here you have your honey and grapefruit soap!
